Wondering how much hp and tq a stock 47re can handle before you need to do modifications?My truck has a rough estimate 300 rwhp,Don't have a lead foot(only every once in awhile), keep up on the on all the fluid changes and get the tranny flushed every 50k miles,also have an tranny cooler!But i've heard they don't like going over stock?!

 

Your there , any more power and your torque convertor will slip not a good thing !!!

 

My son just bought me 70 hp sticks,4 gsk,exhaust manifold,and #60 valve spring for my birthday tomorrow!!Should i wait and get a tc then trow that stuff on or what?!

 

Even stock these trans need a tighter converter and more line pressure. a shift kit is good.

 

Happy b-day give dave a call at goerend trans he will take of you. good man tell him what you want he'll take care of you!!
