Boost gets you........... broke! Haha. Need peoples experience and knowledge on this one please. I had to drive to the Cable Company three times today. About a 8 mile ride down the highway. Blue car has new Eaton Swap and J-mod. I did a WOT 2-3 upshift today on my 2nd trip home so a 70 to 100mph punch. With the Jmod it obviously hits hard and I really dont do that very often. When I got off the highway everything was fine. Fast forward to the 3rd trip home from the Cable Company when I got off the highway the 1-2 was normal at light throttle then the 2-3 never occurred and basically hung up in 2nd which caught my attention. It was right before a stop light so I didnt really think much of it. But when I took off the 1-2 was fine but it hung in 2nd. It almost felt like it freewheeled a little. If I applied throttle quickly it would shift to 3rd and be just fine. If I manually pulled it into 2nd then clicked 3rd manually it would shift to 3rd. But taking off from a stop light letting the transmission shift it self it wouldnt engage 3rd unless I applied more throttle quickly, as in goose it 1/4 throttle for a moment.
I did some research and this is where I need everyones help. Sounds like a 2-3 accumulator piston issue. If it was sticking in the bore I would assume that I would not have any upshifts at all. Correct? Because to be honest I just went back out on the highway and did some heavy throttle 2-3 upshifts and downshifts. And its fine. It hits every time under moderate to heavy throttle. But when under very light to "normal" throttle it intermittently will not upshift 2-3 until I goose it. Once engaged every gear holds just fine under a load or light throttle. Just the gear change is the issue.
Did I tear the seal, damage the seal, piece of debris get into the seal on the 2-3 accumulator piston above the valve body? If so whats the next step. I dont want to drop the valve body again but I assume I will have to. If I do I want to be prepared to fix this once and for all. So, if there are any updated pistons, seals, kits etc I need to know.
Jmod has at least 2000 miles on it since done.
