i ve done the GAB mod and went to the track last night. i think i was in first or second, my rmps actually hit the redline. then my tranny shifted kinda harder than usual is that normal with the GAB mod? i have an auto and ive never acutally hit the redline, usually shifts before...

 

Wat does GAB stand for im kinda new with the maxima and i wanted to start with some good mods but i didnt know wat that means so please give me some help thanks

 

the GAB has NOTHING to do with the shiftpoint (when the TCM sends the signal to upshift).
sounds like a TCM problem

read the stickies for this and many other answers. this will make you look smarter because you wont ask pointless questions that people are sick of hearing. it will prevent you from getting flamed.

Like Soonerfan said, there is already a ton of information in the Stickied threads and you'll likely find many answers to your questions there, as well as learn more about the car.

 

well, my car shifts fine/ smooth when i drive normal, it only happend when i was in full throttle. could it be because my tires were slipping? im gonna put back my stock air box and see what happens. what is TCM??

 

transmission control module...

 

its something electronic thats preventing your tranny from shifting..thats why i said TCM
