    Rear main seal

    There are alignment tools for the front and rear covers. If the oil pan is off, you need to align the covers both up and down, as well as side to side. If the pan is still on, then they only need to be aligned side to side. I've never used one for the front cover, as I have an old harmonic...

    Rear main seal

    Yes it is.

    Rear main seal

    The piece just sits inside the seal, there's no way it can align the cover. As you install it, the sleeve is pushed out, but the cover can still move.

    Rear main seal

    That's not an alignment tool. It's just to keep the seal surface intact. The alignment tool is usually aluminum. You remove the old seal and then when reinstalling the cover, place the tool in where the seal would go. Bolt everything in place and torque. Then you install the seal last.

    Rear main seal

    Yep, if you didn't use the alignment tool, the trans is likely coming back out. Gonna have to redo it unfortunately.

    Immobilizer? Bypass? How safe are these ignitions?

    People would rather steal a S cat Pack Charger than a 20 year old SUV lol. Just about as easy to steal too lol i had to edit how I spelled S cat, it found that to be a 4 letter word hahah!!!

    400th 'front axle not engaging' problem

    Just FYI, if you have a light or a message on the cluster, you have a code. You need a scan tool that can read all modules on the vehicle. The cheap ones only read the engine. You would need a scan tool to read the transfer case module. I picked up one on amazon that does way more than just...

    10Lxx vs 8Lxx vs 6Lxx Replacement for 4L65

    It was already mated to LS engines. 6L80E was in the 07 and up stuff, which were all LS based engines. Yes you CAN make it work, but not with what you currently have in a GMT800. You will need custom work to do it. It's not a simple swap, and certain things may not work as they should...

    10Lxx vs 8Lxx vs 6Lxx Replacement for 4L65

    I'm going to start right off by saying I didn't even read through most of this, so I have no idea how much info is actually in here that you may want. I read the first few posts, then jumped to the end, and despite 30 pages, it looks like no one has been successful with a 6L80E swap yet...

    4WD to AWD Swap

    I didn't have the front emblem done yet, this is the only front view of it I can find. I plastidipped an old one from the junk yard to see if I'd like it or not. I have another one that I'm planning a bit of a hybrid project for. I'm going to keep the grille from the denali, but remove the...

    10Lxx vs 8Lxx vs 6Lxx Replacement for 4L65

    There are guys dumping more than 600hp through a well built 60E. What specifically are you looking for? Just more gears?

    10Lxx vs 8Lxx vs 6Lxx Replacement for 4L65

    I've looked into this before. It's way too much of a PITA as it requires a separate TCM to control it, where our 4L60E is controlled by the PCM. Everywhere I've seen, it was determined to not be worth the hassle if it's even realistically possible. I'm pretty sure the communication bus is...

    4WD to AWD Swap

    That thing is $100. The whole actuator is plastic and it's held up for........ who knows how long. It's pretty thin plastic too. This PVC will outlast that actuator plastic.

    06 Silverado Crew Cab Build

    OK, I got the first mod tune file installed last night. I installed the NP149 driveshaft over lunch break, since the 246 driveshaft is about an inch too long to fit. I pulled the actuator and installed a 3/4" long piece of PVC to lock the front axle and no fear of the actuator backing...

    4WD to AWD Swap

    OK, project done. I got the NP149 driveshaft and installed it today. Found out my park brake sticks lol so I had to free that up to move it in the garage. I also removed the actuator, and installed a 3/4" long piece of PVC pipe to keep the front axle locked. I kept wondering if the actuator...

    Blackbear tune... I'd like to hear from personal experience to set up

    Oh, gotcha, you meant the full process. Yeah, I get what you mean.

    Blackbear tune... I'd like to hear from personal experience to set up

    Flashing the ECM never took more than a couple minutes for any of mine.

    Propping Hood Vertical

    Use some kind of stick/piece of wood to prop the hood in place. Remove the bolt at the top of that hinge on both sides. Then push the hood back and prop it in place with a stick/piece of wood. I just did this when I swapped my engine last month. Would definitely be easier with 2 people, but...

    2005 XL Rust Repair?

    These vehicles are cheap enough. I wouldn't bother sticking lots of money into rust repair, you'll quickly exceed the price you could just buy another one for.

    LQ9 6.0 into a 2001 Yukon XL - a couple questions

    The easiest way to do this is to take the flex plate and intake manifold off the LQ9. Remove your engine and drop this one in using those parts from your old engine. The LQ9 will bolt right up to a 4L60E, just make sure to use the 5.3 flexplate and the torque converter will have no issues...

    Blackbear tune... I'd like to hear from personal experience to set up

    Your tahoe PCM shouldn't be any different than other ones. I'd send them an email and see what's special about yours. I just looked on there actually, for the 07-08 Tahoe, I didn't see anything special, other than 07+ is recommended to use at least 89 Octane due to higher compression. As far...

    Blackbear tune... I'd like to hear from personal experience to set up

    You shouldn't have the vehicle down if you're just getting a tune. Depending on how you go about it, you can have them A. send you a PCM or B. send you the equipment. You download the stock files from the PCM and email the file. They send you a modded file and you flash it to the PCM. Then...

    Determining Actual Mileage

    Yep, according to NHTSA...... "If the odometer mileage is incorrect, the law requires a statement to that effect to be furnished on the title to the buyer. However, a vehicle is exempt from the written disclosure requirements if it’s 20 years old or older, or a model year 2010 vehicle or...
