sorry i meant to write 4l80e how much hp can this transmission take on?? can i put it into a low gear manually like a stock auto?? sorry im a 6 speed guy just getting into the auto for my f1r prochager project. im thinking about using this set up

 

I have one and it should handle what I can throw at it without a problem Frank seems like a good guy and has givin me great customer thus far on some questions I have had for him on certain things. Im gonna see how it does when the track re opens at the end of feb or early march.

 

so it will be able to handle high 800 or low 900rwhp??

 

I would have to say yes , You have to remember before you even touch these they are strong, They live in trucks towing 10000 plus pounds for years when in a car they are almost on vacation.

 

people in a above thread are bashing on the quality of performabuilt. hope u join in it to solve everything
