I have been mulling over all kinds of possibilities for The Beast as well. LS swap into a jet boat with a blown 6.0 and part the rest out? Sell it without a transmission? Fix it and keep it? Or sell it? I just don’t know. Anybody want to make an offer? :emotions33:

I decided I’ll swap the wheels from The Beast to the Tahoe and that way I wont be able to stand to look at it like that and I’ll start on it. I figured to wait until after all my cancer treatments are done anyway and today was my last chemo infusion and next Monday will be my last day of radiation at which point we are calling it a win. there is no way to ever know if bladder cancer is in complete remission because there still isnt anything that can scan for cancer in a bladder with any real certainty. The only way to check is to go inside with a camera and look, and biopsy as well as they can look for cancer cells in the urine. So every 3 months for the first year they’ll look, and once a year for the next 5 or more. I’ll have all summer off, and in September I’m scheduled for them to put me out when they go in for the first look. My urologist wants to be ready to remove anything just in case there is anything. So just to summarize, July I peed bloody urine and freaked out, went to urgent care. They ordered a bunch of tests, sent me to a urologist where he went inside with a camera and I watched as he found 5 tumors, once of which was right where my prostate touches the bladder and looked way different than the others. It turned out, that one was small cell bladder cancer, a super aggressive type that had them immediately decide to remove my bladder and prostate and they started talking about being up against the clock. They also determined that I was stage 3 due to this. I did a quick check- small cell bladder cancer by itself has a 40% survival rate over 5r years. And I also had that second type of bladder cancer- which further complicates things. Very little is known about the small cell- its only 2-3 % of bladder cancers detected. And so even less is known about having both types. I did my research, weighed the pros and cons of different options and asked my oncologist if trimodal bladder saving treatment was viable for me. That would be surgery to remove tumors, regular full 12 week chemo regimen followed by 4 weeks of light chemo every Monday with combined with radiation to the bladder and prostate which is done Monday-Fridays then follow up checkups if all goes well. This round is only a 20- minute radiation dose. The drive is the worst part of that. So I’m nearly at the end of treatment, the rest will be a cruise. Today was from 8:30 this morning to 5:30 and then the drive home. Mostly sitting around and visiting with my sister who I haven’t spent enough time with the last few years. Anyway, thank you people for being part of my world. A car forum might seem like a strange place to read about someone’s cancer but my build threads will be here forever, I’m not doling out personal info and this place has always been a cool and safe place for me for many years. And I want this journey I;m taking to be open and a part of who I am. My advice for anybody is to advocate for yourself especially when it comes to pushing to get cancer screening if you fall into any of the high-risk categories like I did. I smoked cigarettes for 40 years as well as drank heavily. If it’s caught early enough it can b e cured, unfortunately insurance companies in the US think its better to put out fires rather than prevent them so its not being caught until its stage 3-4 when its too late because they deny imaging or tests. Anyway, 5 more 20- minute radiation blasts and I’m done! If you read all the way through this long ass post , I thank you. I’m still here and will be for the foreseeable future so if there’s anything I can help with in regards to your GM SUV or pickup, let me know. :happy107: :favorites37:
Keep up the fight brother! Thank you for sharing with us, as in many of your exploits, you're an inspiration. God Bless.

Thank you Sam! This morning is my last radiation treatment, and I’m done! My sister has been my chemo partner and drove me to nearly all my appointments ; she is going to be with me this morning and I’m ringing that damn bell so other cancer patients can see it can be beat. 2 bladder operations, 12 weeks of chemo, 4 weeks of daily radiation. And now I get the summer off. I will have to be checked via cam up my dick every 3 months for years and every time will be nerve wracking. I have changed how I eat and exercise as well as how hard I will allow myself to work. I’m 65 and need to realize I need to take it easy on this old body and not push too hard. Last summer I worked myself to exhaustion for months digging and building my pond. I lost about 40 lbs and wasn’t eating right, purposely trying to lose weight that way. Not a good idea. I believe I put my immune system at risk and that’s when the cancer invaded. I will keep myself strong and healthy and that shit wont have a chance. :p

Well well well. It’s my birthday. 66 today. And today I decided the fate of The Beast. It’s been a helluva summer and I wasn’t able to devote enough time to even attempt to work on this. First there’s the cancer thing. It’s ongoing and will be for as long as I live, at least the looking inside my bladder for it. I have a few more weeks before the next scope. Hoping for more good news there. Then I spent a few thousand on some big beautiful Koi from Japan by way of Hawaii to reward myself for finishing my cancer treatments. That had turned into a big mistake, half of them are sick and I’ve been dealing with learning how to be a fish vet and still had to find out what bad bacteria got into my pond and why and how to fix it. So yesterday I decided I at least needed to diagnose the problem. I figured the worst that could happen is I find out it is the transmission like I feared or not the transmission. Could be a birthday present of sorts with some great news that I don’t have to pull the transmission and send it to the East Coast.

So……I put it up on jackstands.I connected the rear driveline and started it up, put it in gear while a buddy watched the rear wheels. It immediately felt just like it had when it stopped driving- like I was holding the brakes. I revved it up a bit and the left wheel started to spin, I could see it but I really had to give it the gas just in order for that wheel to move at all. The right tire never moved my buddy said. So I disconnected the rear and connected the front driveline and started it up. Those wheels both spin freely in drive at an idle. With both drivelines disconnected the trans and transfer case turn fine in gear at an idle or revved up. I didn’t want to let the transfer case spin much without all 4 wheels connected. So its the G80. I did install a girdle if you followed you’ll remember. That girdle was supposed to brace the main bearing caps in the G80 because that’s where the weak point is especially when running high HP. So I’m not sure what exploded in there but something must have.

My plan now is to find a junkyard differential and maybe buy some wheels and tires that fit over the Wilwoods without using 2” wheel spacers, and probably sell it. I’m liking the Tahoe I put together at this point and am trying to move in a more relaxed quiet way. Yeah right. I’m just more stealthy now. I barely drive anymore and someone else should enjoy this thing because it is an absolute blast to drive. It’s just so hard to not be crazy in it. Sigh.

Happy Birthday Mark!!! And many, many more to come!!
Well, and blown rear is better then the trans going. Mine went out too. I was able to source a rear for a decent, so their not terribly expensive. Wish I was local to you, I would've loved to have some fun in The Beast! I'd still keep it if I was you.

Thanks for the birthday wishes friends. I found a guy local who has an 02 Tahoe G80 with the same gear ratio who will pull it and sell it for $200 so I’ll grab that in a few days. Meanwhile I just found 4 used but look like new 22 x 9 black reps, just like the ones I swapped onto the Tahoe, for $700. I’m supposed to get those tonight. That way I can buy new tires and TPMS sensors for the new set and install those on the Tahoe so the idiot light goes off, and then The Beast gets its original wheels and tires back.

Happy Birthday, and you're still a youngster, until there is at least a '7' starting your age number.

Happy birthday Mark!

Also, I've broken my share fair share of g80s in f-bodies. Ive never had one do what youre describing. The pin has typically broken then chews the gears up, which results in either a jerky ride home or being towed home. I suppose its possible that something broke and has it locked up tho.

I hate to even ask, but are you 100% sure it's not a locked up caliper?

Obviously I havent followed along closely, so disregard if this has been discussed.

It’s not a locked up caliper. And it’s not the rear differential. It might be the transfer case. This has the NVG249 full time AWD TC with a viscous coupling that I know very little about. It’s weird and hard to diagnose without a lift. I need to make a list of things I’ve tried and the results because there’s been a lot of diagnosing. It seems if all 4 wheels are on the ground I was able to drive it forward for 10 feet easily but it was hard to back up those ten feet, and then I went forward about 5 feet it seemed even harder, and I had to give it a lot of bas just to back up that little bit, and it just stopped in place and wont move again. The first time, after having it towed home, I disconnected both drivelines and I was able to roll it back and forth in my driveway with 2 people pushing like normal. Then my first troubleshooting I hooked up the front driveline only and drove it back and forth several times in the driveway. Then I thought the rear differential was locked up because I hooked up the rear driveline, all 4 wheels off the ground, and it wouldn’t spin the tires giving it a lot of gas. The right rear never moved. We tried rotating the tire by hand and it was locked up. I thought it was the diff. So I started removing the diff and when I pulled they right rear caliper off, I was able to rotate the hub by hand. It must have rusted up sitting all winter. Crap. bad diagnosis! So now everything was free, I hooked up the drivelines, wheels off the ground, and it spun the wheels forward and reverse, but something was off. I had to give it some gas to get the wheels to rotate, and they never seemed to spin easily and it felt like there was something making a chunky weird noise,. I had to reassemble shit and put the truck on the ground for more testing and drove it forward and back like I first mentioned and eventually it just quit moving, like suddenly the brakes were on. I checked that rear caliper and that wheel spins by hand when I jack it up. Also, when I did drive it forward, it felt like I drove over a 2 x 4 in the driveway. It was another weird feeling because there was nothing in the driveway. I swear it felt just like I had driven up against something and I had to give a bit more gas and then it just kind of jumped and started moving forward. Like I said, its hard to diagnose but I’m almost sure its not the trans.

OK. With the wheels off the ground, I can put it in drive and let off the brakes and at an idle all 4 wheels are turning and I hear no weird noises. I only did this for as long as it took to walk around it since you’re supposedly going to damage the transfer case if you do it much. But when I lowered it to the ground, it drove forward but I heard and felt that noise/ jump and after about 20 feet it started feeling like the brakes were on and I put it in reverse and had to give it a lot of gas to get back the 20 feet. I didn’t push too hard for fear of breaking something else. NVG249 transfer case viscous coupler toast? Anybody have any ideas on how to diagnose ?
Edit: I think I’m going to try it with the rear driveshaft only connected to see if the rear diff binds and if the transfer case operates ok with the front decoupled. I did it with the front one only connected and iirc it drove forward and back the 20’ OK. I’ll do this again also. And this time I am going to take notes.
edit 2: its the NVG 149 transfer case, there is no 249.

If I have The Beast info right, see:


or use the links at the top of the browser to navigate to the correct drivetrain.

Then expand the section for the transfer case. Maybe some of the symptom-related diags will help:

Yeah thats the correct info but uts pretty useless like a lot of the service manuals is when it comes to some of this trucks components. The NVG149 is not well documented and since it was only bused a couple years there’s not much on the forums about them. Maybe @randeez can chime in- I’m know he was running one on his race machine. I looked through the service manual but it doesn’t show a diagnostic for my situation. And then troubleshooting they do show for other symptoms pretty much says to open up the transfer case and look at the internal components. So much help there lol.
