My 4L65e has experienced what I believe to be total 3-4 clutch failure. Everything is fine until 3rd gear where it acts like it's in neutral. I've been having issues for a few years now, so it's no surprise, though I was hoping for a little more life out of it, I did just hit 250k though, and I'm pretty sure it's original. Plan is to rebuild.

Should truck be parked and not ran or can I drive around in 2nd gear? This happened a couple weeks ago and there were a few days where I had to get to work and had no other option but to drive there in 2nd. I did my best to not exceed 20mph, but some streets I had to go 35 for a short distance here and there or be killed. Will driving like this do damage to the 2-4 band or anything else?

I've been quoted $3500 by a shop that came highly recommended, is this within the normal price range for a rebuild? It would be a stock rebuild with parts that fix the inherent weaknesses of the transmission. Included removal and installation. That's just the starting range, it could go up or down depending on what they find. Based on talking with him though, rather, him going through his spiel without much room for input, I feel even more uncomfortable bringing it to a shop than I did before. I want this to be a one and done, and done the right way, ordeal. Everyone I talk to seems to not have much time, not really care, or they aren't interested in having a reciprocal conversation. I'm probably going to be tackling this one on my own.

Besides a transmission jack, a dial indicator, a T50 Plus socket, and a good set of snap ring pliers, are there any other tools, specialty or otherwise (beyond the normal tool set items) that I should get? If there's a tool that isn't technically required, but that makes the process go along much smoother, I'd rather opt to get the tool.

Where's the best place to buy parts from? I assume FLAPS are out of the question. From what I've seen thus far Sonnax, Transgo, Alto, and Raybestos are the brands that are mentioned most. Seems like neither is on the whole superior than the other, rather they each have certain parts that they excel at. I mainly purchase all my parts from rockauto, should I stick with them or are there certain parts I should purchase elsewhere?

I haul (gravel, pavers, etc.) more than I tow, but would like to be able to comfortably tow when I need to. I don't necessarily abuse the truck but I drive spiritedly, and with purpose. Engine is a stock 6.0 LQ9 with no major power upgrades planned.
What parts need to go to a machine shop?
What parts should definitely be on the upgrade list?
Should I replace the torque converter?
Is it better to buy parts a la carte or get a rebuild kit and supplement it?
Should I open it up and check everything out before ordering parts? I'd like to have as much ready beforehand as I can, but I get that there is no crystal ball to ask here.

There's so many options for so many parts and I'm not sure what's worth getting. I don't want to get the same parts that failed on me already, but I also don't want to spend extra money unnecessarily beefing up parts that I didn't need to. A lot of what I'm seeing is for the 4L60e, will all these work in my 4l65e?

@NickTransmissions, I tried to pm you but wasn't able to. I've seen on other posts that you allow trannys to be shipped to you for overhaul and you ship them back. What's your current lead time looking like? What would be a ballpark range for cost? Are there any shops in the Phoenix area that you know?

TIA

If you dont know that you ALWAYS replace the torque converter during a tranny rebuild then you are NOT ready for a tranny overhaul project. Trust me, You dont want to practice on a tranny that YOU need to be reliable and work correctly the first time and every time. If you cant find a shop locally that gives you warm fuzzies and wont even take the time to talk to you about it all then take it out of town and find a place that will. $2500 for a complete R&R is not beyond a normal average cost.

Not saying you don't have the ABILITY to figure out how do this as I do not know you personally. But, agree with Rockola on this one. If you have to ask if the TC should be replaced you are not ready for this job.

Also, a reman with a warranty is always a good idea. Especially if you are hauling with this thing.
Oreilly is showing 2300 to 2500 for a 3 year warranty reman. Not too bad. I paid 3000 installed 6 years ago.

Ok... so what do I need to do to be 'ready'?
You should have a seasoned tranny builder that knows your model tranny standing next to you during your rebuild. Again, you dont want your tranny to be the science project that you figure out that you didnt do it right the first time. Its not hard but its also not easy, especially if you dont know the standard checks to do during the teardown AND the build process.
