my trucks bouncing off the rev limiter at 5,500. i dont think thats right. im thinking the guy i bought my transmission from brought the rev limiter and redline down a bit, possibility? or could it be something else. just got my new pump in, and its still hesitating, i was hoping that would get cured. it slipped pretty bad going into second on one wot run, i think it was torque management.

 

Did the guy you bought your transmission from tune the truck?

 

he had it hooked up to a device of some sort, it wasnt a laptop, so i dont know if he had that capability. it just used to run all the way up to 6 grand

 

i cant even make 85 in second. it shifts at like 75 wot

 

sounds like you need a tune adjustment. 5500 is low... seems like a stock limit.

 

id love to get it tuned, but i wan to put a cam and change the injectors, first

 

What year is your truck? the NNBS have a separate computer for the 6L90E's. Well in any case, it's in you tuned, you can get yourself in some trouble if you wait on that.
