TransGo 700 Performance Shift Kit Problem

I am posting this only for information. I performed many searches using this forum, Google, etc. and could not find a solution to my problem. Hopefully I will include key words that will be recognized by someone searching this same problem on Google or similar search engine.

I installed a TransGo shift kit in my non-lockup 700R4 (FYI - same kit for lock-up or non-lock-up). I followed the instructions and video exactly. I checked and double checked each step along the way. I put in a new filter, put the pan back on, filled it with some fresh fluid, started the car, topped it off and put the trans into reverse. The result of all my hard work - NOTHING! The car would not move in reverse and barely moved in any forward gear.

I called Transgo and received a very agitated technical guy. His attitude really pissed me off, but he suggested that the TV boost valve snap ring was not fully seated and the assembly fell out. I drained and dropped the pan to find the snap ring and other TV boost valve pieces lying at the bottom of the pan. I reinstalled the assembly and snap ring for a second time. This time, it was a little better, but something was still wrong. I hooked up a high pressure gauge and discovered my pressure across the board was about 50 psi. I drained and dropped the pan again. This time the snap ring was dropped, but the assembly did not fall out. I invested in a set of long reach snap ring pliers and tried it for a third time. This time I employed the help of my oldest daughter for a third arm helps when reinstalling the TV boost valve assembly and snap ring while the trans is in the car. It is installed vertically, and gravity is not your friend when trying to hold up the TV boost valve assembly which is under spring pressure and install the snap ring up inside a tight diameter opening.

Anyway, third time was a charm - so far so good We should all learn from other mistakes and mishaps. After all, isn't that the purpose of an awesome message board such as Hotrodders? Ed.

HEY EDGE: Great post!! I would hate to admit in public all the parts that I have put in wrong, upside down, backwords, wrong side of the car. The best solution is keep trying until you get it right without throwing tools or taking The Name of The Lord in vain....................... ....DAVE
