Hello all.
I've conducted diligent forum searches but haven’t found an appropriate answer. I recently picked up a 1997 M1097a2 with the 6.5l and a 4l80e. Further inspection shows water intrusion into the transmission, likely from a missing dipstick grommet. I rolled the dice and attempted multiple system flushes to no avail. The trans is done and I need advice on my next step.
I'd like to explore a junkyard 4l80e swap, but can't find a definitive answer as to which donor vehicle/year would be an exact swap, aside from the tailshaft. I believe I have the 'new' version 4l80e with the cooler lines towards the rear. I see there's some issues with the civilian TISS/TOSS rings, and If I'm going junkyard swap I want an easy swap without having to change internals or buy a new TCM. Is there an easily identifiable civilian 4l80e that is a direct swap?
If not, I intend to rebuild the transmission myself. I've never done an auto rebuild but this seems like the perfect scenario and I'm confident in my skills. Can anyone recommend a good rebuild kit and hopefully a detailed video?
Thanks all!
