Ask me soon: How'd the TransGo A606/42LE shift kit work out?
I just installed the TransGo kit in the tranny in my 94 Intrepid. The rest of the car is still in pieces on the shop floor but since I had the engine/transaxle out anyway I thought this would be the ideal time to do the kit. I know it CAN be installed on-vehicle but retaining the pistons isn't fun while removing the valve body, and reinstallation is tricky as well, so I elected to flip the transaxle over on its top and do the job the easy way.
One thing of note, I did NOT do anything with the pump gasket/seal or anything in the front of the transaxle. The instructions that came with the kit treat this as an "optional" bit, saying that if the engine is still in the vehicle, to simply skip the page dealing with that particular set of upgrades and moving along to the seals/expanders/spacers of the accumulator pistons elswhere in the transaxle. I COULD have done this part of the process but I have bad memories involving accidentally unseating the torque converter, failing to get it oriented and seated before bolting the transaxle back tot he engine. I would much prefer to keep the torque converter in place this time around, so I've skipped that part.
The rest of the install wasn't difficult. Mine was a valve body without a "bathtub", which I learned is merely an elongated hollow (like a bathtub) for a check ball. The rest of the holes for the balls are round. I did drop my check balls, but retained them all and the diagram showed exactly where they were supposed to go. I also checked my torque converter clutch hydraulic switch valve as I was suspecting an issue in this area, however it is free and not showing any wear on the annodized side surfaces so I am satisifed there's no issue there.
I, of course, replaced the fluid filter and o-ring and ensured that the retainer clips were properly positioned and tightened down when I re-assembled.
In the next few weeks I'm going to re-assemble the car with its replacement engine and give it a test. Then, assuming everything turned out okay, I'll be happy to give advice to anyone else doing this upgrade.
