Hi All
My winter project is to rebuild my 4L60E and install it in the spring before camping season starts. I haul a 5000lb trailer around and I live in the mountains so I need a strong transmission to make it home.
The original transmission failed 30 miles from home after a 7500 mile road trip and I nursed it into the driveway in 2nd. We climbed 7 or 8 mountain passes in the last two days and it waited until we were down the last one and on the coast before it started slipping. I couldn't have been more grateful.
I've swapped that transmission for a low mileage unit from the wrecker and it's been performing fine. We did three weeks in the mountains this year without a single problem. But I want to rebuild the original (I kept it when I swapped them out).
The plan is to rebuild the core I have and then swap it into the Envoy. Then I'll rebuild the unit that came out and sell it to try to recoup some of the $$ I spent on tools. Then maybe find a few more to rebuild just for cash to try to come out even.
The 4L60E is so ubiquitous I should probably own a few more vehicles that use it so any skills I learn here will be useful on future vehicles. The tools are expensive but I've never made a car payment in my life so I can afford to spend some money each month on tools.
I'm looking for help and advice from those with knowledge and I'm hoping to post details and solutions for others to learn from as I go along.
