Ok so sometimes, granted only sometimes, 20 % of the time I'd say if I am at wide open throttle, my car won't shift it'll hit the revv limiter and just say pinned unless I lift off the gas for a second then mash it again, it's an 05 with a 3.4 pulley and supporting mods, zzp PCM and a zzp s/k I have been thinking it could be a pressure control solenoid, or could it be the springs for my accumulators? I was disappointed when my zzp kit only had plastic shims where I think it was the trans go has new springs too, could this be a spring issue? A pcs issue? Or something more pricey... Or is it my zzp PCM not being tuned right? I've been thinkin all 3 things... Also if I do have to change the pressure control solenoids, are there any hard parts that I can swap out while I am at it? I've never had one of these trannys apart so I'm not sure. But it would make sense to swap a pump shaft or something out while I tear it apart for the solenoids, if that is the case... Thanks for your input.
