youll want a 97-99 80e though you can use later years with some trial and error, later 80e's have the IMS to elim that issue, its easy as hell to swap the harness and IMS in (ive got one ive removed already, boxed up and ready for the 442) i never got too far into the lack of a tcc pressure switch, presumably you can delete the code diagnostic and the tcc will function just without triggering the code and the hot/failsafe stuff.

Is that a good year.

Like Snowflake said what's the best year, anyone know ?
the early had issues with the castings warping so many of those are GM reman. you do not have the pressure switch manifold so your gonna have some work to do with the obd2 pcm but your trans controller likely doesnt have any diagnostic capability so it wont use em. we have a nearly new GM reman from a 94 deville with 165 on the clock, trans probably has maybe 20k barely any oil staining on the GM grey paint and even the alum reman tab wasnt corroded. i will swap out the vb and harness if i have to, regardless its a goldmine of new parts.

ive wanted to play more with the trans type in tiny but ive got two 80e pcm's here that id love to see if i can pull any data from. i kinda wonder if changes in the bin file might be affecting overall trans strategy...its possible he just has a weak trans so im interested in what dave finds out. the inverter never had any issues aside from ****head not sealing it up against saltwater.

i never got dave to tell me exactly what he did with the bin file lol maybe he can take care of the pesky tcc switch issue (though manual operation works fine)

ultimatly you suckers are helping jeff, me, dave, and the canuckian's, blaze the trail.....hahahah

thanks! lol
