Hey Everyone,

ok heres the deal I got a 2002 RCSB Z71 5.3 Powerdyne pushing 9PSI headers, flowmaster, 255LPH Fuel Pump, 42lb Injectors, custom tune, functional ram air hood. I think I have a 4L80E transmission but I aint sure how can I tell? Also I have read about everyone putting corvette servos in there tranny where can I get one for a 4L80E? Also would I be wasting my time to put in a shift kit if I install a servo. Or would I be wasting my time to do either one if I have a custom tune?

 

shift kit, seperator plate and servos are the very minimum mods that you should do to your transmission.

 

you dont have a 4l80e on a rcsb z71. you have a 4l60e.

 

im putting in corvette servos and a boost vavle to up the pressure in my trans. You get as better 1 2 shift

 

good luck in putting a vette' style servo in an 80E.

 

If your truck is a 1500 it is a 4L60e..... You'll need a transgo-shift kit, vette servo and should be aight for lil while.

 

Z71? yep 4L60E,doing a vette srevo you get a better 1-2 from the apply and a improved 2-3 shift from the accumulation,A vette servo is a first thing must have to hold that band tight on the drum.Trans-go is the next step if you do them seperate.

 

I know that a 4L60E come in my truck stock, but I blew the transmission in the truck while under warrenty and I had been having tranny trouble since I owed the truck and I think they said they were going to upgrade my trans to solve the problem to a 4l80E but I am not sure if they did thats why I was wanting to check.

 

Never happen


well shouldnt say never, they may say well swap it but you have to pay the difference of 3k$

 

You can always look at the pan.
