I have been doing LOTS of research and I can find any sure answers on some things. Here is what I have and if yall could tell me If I have missed anything I would sure appreciate it!
I have a 97 Z71 1500 Vortec chevy pickup with a SAS 25" lift and 44 inch tires and the 4L60e has gone out (Imagine that) my good buddy has a 4L80e out of a 94 3/4 ton pickup with a 454 that he said he would sell me for a hundred bucks and help me put in, its been sitting under a tool shed for about a year(ideas?) but I have talked to him and the guy he got it from and they said it worked fine when they took it out (the motor went bad in the truck)
First off I am wondering If this will work? The guys at nelson performance said it was definitely do-able. Here is what I know
-I have the 32 spline Input gear for the T-case (guy my buddy got the tranny from gave it to me)
-I can get the necessary wireing harness from nelson performance.
-Moving the cross member back is no big deal
-My buddy helping me has a shorter driveshaft for the back I can have
-two dealership around here said they would tune it to run the 4L80
-It has a torque converter on it.
-I have a dipstick tube and the dust cover.
Here is what Im not 100% sure about
- Is it absolutely certain that this tranny will be compatible with this truck and that the tuning is no big deal? I have seen that sometimes tuning is not necessary and I have also seen that $1000 controllers are sometimes required(is that only on carburated motors?) please let me know if you know anything about this.
- The flex plate issue has me a little confused, Can I use the one in my truck or do I need one out of a 6.0 litre truck? (the guy my buddy got the transmission from has one he will sell me on the cheap) and whats the deal with this spacer required? Im not in the know on this so if someone could let me know exactly what the word is I would really appreciate it!
- Also I don't have access to a lift and since the truck is so high up (40" from the ground to the bottom pan of the transmission) I know a floor transmission jack wont reach and that a stand up transmission jack is to tall. Any ideas? Thanks!
