My brother bought my SS and has since modified it more. It is pushing ~ 420 rwhp and he has a NX 100 dry shot on it. He has a SS3600 and the stock transmission is dying. It slips very badly in third gear. He wants to get a good dependable transmission for street and strip but when he is driving it on the street he wants it to be relatively comfortable. What are you're suggestions and experiences. I'm looking at FLP and considering the RPM transmission that Thunder sells. Any help will be appreciated.

Look good and hard at the FLP stage 4 should be all ya need!

 

th400, th350, 4l80e. Pretty much anything but another 4l60e(Just a waste of money).

 

Some people don't want to go threw the hassles of swapping a lot of stuff though!My be easy but A little involved plus if the 4l60 is built right it will be fine!

 

Yeah but if built RIGHT you will be wasting you money.
