I was following this thread because I also just have line pressure upped without a shift kit. When I install the shift kit should I bring the line pressure down again as well back to stock? TIA

Yes, get all your line pressure tables back to OE.

without a doubt, a shift kit is a must.

i thought that plastic 1-2 accumulator piston looked a little shady. i knew i should have replaced it. all well... how will i know if it breaks?

no washers still give a nice firm 1-2 shift. i love the shift kit. it also down shifts a lot better and with less throttle.

does that kpsperformance sell the piston I need?

How much would the labor on the install of that piston and shift kit be?? If I could do a couple little things now to prolong the tranny life that would be great. If Im going to have to pay to have the whole thing cracked open and reassembled I guess I'll what to get the money to do the FLP. What would you suggest?? Sorry to jack the thread, but thought this may interest you as well

I'd say labor around $250-400 for a shift kit install done correctly. I'm always scared of cheap labor usually equates to poor workmanship.

The TransGo will prolong the life of it by a good amount. The money it's going to take you to install it all...that could go toward an assembled off the shelf unit.

if you have a grinder, do it yourself. its not that hard. its kinda like legos. watch the video a few times - but follow the written instructions. the hardest part for me was taking the snap ring off.

hitman: have you heard/seen any broken plastic acc. pistons? im worried now.
