Hey guys,
A guy with a junk addiction can only go so long without wanting to buy something, so Guess what I found!
1993 C2500(HD) ECLB Gloss white body/gray interior pickup with presumably plenty of miles, as it has a completely shot 4L80E. few if any dents, and little seat wear, so a highway rig.
Now knowing that I have to have a 1995 and earlier 4L80E (91-95 had different wiring and controls, correct?) due to wiring, and the realization by some (Warwagon) that the 4L80E isnt a bulletproof towing tranny got me wondering, what does an Allison swap entail?
surely as far as electronics go, older is better, right? so for a cheap, easy swap I am limited to a 5 spd from 01-05?
how is the computer setup? are they standalone computers integrated to the GM truck, or is it all integrated? If it is integrated, who sells the best bang for the buck standalone controller?
would any working 5spd takeout (for example, a 200K+ miled one out of a rollover for instance) hold up great with no modification whatsoever, and just fluid and filter change behind a 93 6.5L? (provided it was cared for to start with)
most importantly, will it fit in the tunnel? keep in mind, everything will be 2wd. minimal hacking preferred.
what would cooling entail? does it need a better cooler than stock 4L80E? (as in are the fittings big enough)
finally, what would the linkage be?
the truck right now is 700 bucks, so the goal is to make it as low buck as possible, but still try and do it right.
This is just a maybe deal, so dont spend too much time writing me an install guide!
any input appreciated,
thanks folks!
