I recently bought a dynamite .28 and put it in my slayer. Broke the engine in and tuned it, engine runs great and so does the truck. My only complaint is the transmission now erratically shifts. If you roll into the throttle it holds first for a very long time then shifts, but if you give it full throttle right off the start and try to do a launch, then the trans immediately shifts. It also shifts if the wheels arenít making full contact (going over many bumps). I have messed with the adjustment on the shifter for a few hours and this was the best I could get it. I checked the shifting mechanism and all of it is working right. Iíd imagine this is a consequence of going with a bigger and more powerful engine but I was wondering if anyone knew of a fix or an upgraded shift mechanism that could possibly eliminate this and make it shift consistently. Any help would be appreciated.
