Gonna be finally buying this 1991 V1500 suburban ive been looking at for about a year now. its got a GM goodwrench crate engine, guy lost his license shortly after the replacement engine went in, then got caught driving it and then parked it. the body around all the wheel wells is all rusted out, but its got all the bells and whistles of a 1991 suburban which i intend to transplant into my 1988 V20 build. Anywhos. The Gm literature from the online heritage page says all R/V 1500's and 2500's in 1991 (suburbans anyways) came standard with the same transmission the 4L80E.... now does anyone have the RPO code that would be in the glovebox or a quick visual way to identify if its actually the 4L80E and not the 4L60E? My idea is to take the adapter and transfer case if it is the 4L80E and bolt both to my 1995 4L80E i installed. my Np208 grenaded and dont have the time right now to learn how to rebuild it, so i figured parts truck for $400 for engine, trans, t-case, axles, driveshafts (particularly the front one to the corp 10) , then all the doors and windows, plus the 1991 front end was well worth it.
Right now just need a way to help my friend identify for sure whats in it, since its been 6 months since i saw it and the phone that had pictures is long destroyed (due to work of course) its over an hour away so i cant just stop by and see it right now.
Also any reason my idea wont work for the front driveshaft and the tcase/adapter?
