what transmissions came with what year trucks? i think i remember looking mine up and i thought i had a 4r70w in my 95. im just wondering because i was looking at shift kits but then when i found out about the punisher valve body i got interested. especially since their not much more than a shift kit. the punisher valve body says its for a e4od though?

any help? my trucks a 1995 supercab flareside, 5.0, auto, 4wd. ill look for my code tomorrow for sure though.

 

if your 95 is like mine,it is the 4r70w,trans code u

 

Yep i got the u code. I guess no punisher valve body for me.. For the 4r7ow do you all recommend a shift kit from b and m or a valvebody? What about other mods for it?

 

With the 4R70W, forget about a "shift kit" and read up on/do the J-Mod.

A good, large transmission cooler is another wise investment.

 

Dont the trucks come factory with a transmission cooler?

 

ive been reading up on the j mod and their seems to be alot of controversy on it. some say it leads to tranny failure in the trucks do to the sperator plates and valvebodies being different in the trucks.

what about the factory tech seperator plates? ive read alot of good things on those.

 

also the b and m shift improver kit looks like thats all it is. the seperator plates and maybe some new springs.

 

you might contact lew52 on here. I know he is running a high horsepower 5.0 with the 4r70w and I think the only mods done to the tranny is a shift kit.

 

I forgot all about lew but ill get right on that!
