definitely. I'd love to get details on the TCM and what parts are used to make it work with the 4bt. IS it completely stand alone transmission? does it use a TPS, etc, etc. This was why i avoided the 4l80 when doing my swap, for the cost of a rebuilt trans and an aftermarket controller you are looking at about 3 grand easy.Checks in the mail! Actually, I bought it for someone else. That's one heck of a deal for anyone looking to replace a clapped out 6.5/4L80E.
sounds good, part numbers would be sweet.The one 4BT/4L80E setup I've seen used a TPS, but not sure on the details. If you guys are interested I'll post up the details of this tranny controller when I get it within the next couple weeks.
You are correct, the 4L80E has a "stand alone computer" when built with the 6.5 turbo diesel from 1991 untill I believe 1994(whenever the engine became computer controlled)I have heard that certain year chevy diesels with the 4l80 have the seperate controller and will work, but haven't seen any definitive information.
would this be the chassis control box? that's all i can find on car-part.com They say it's located on the right side of the dash.90-93 ish 6.2 and 6.5 GM diesels with the 4L80E had the stand alone TCM. The 90-91 ECM and harness is preferred for the speedo VSS on the tailshaft or transfer case and of course those year model transmissions for the same reason(VSS). The 90-91 3500 1ton trucks were available with a NP205 also.
Lockup converter, OD and stand alone TCM/VSS usable for speedo etc. And...NP205. One of these will do for me when the time comes.
I recently watched a 4L80E/NP205 sell on Fleabay for 1625.00, not bad IMHO.
the 700r4 does work, i have driven it about 40 miles so far.the 700r4 may hold up, if you REALLY beef it up. then you have to mod the TQ adapter ring.
a 2wd 4l80 e can be converted by changeing the output shaft.
a used 4l80e is 650 around here (4wd). the computer is 900 for a compushift. tq converter is 300.
isnt a 700 around 2000 for a "beefed" up one? then 300 for a tq converter.
the 4l80, without a doubt is stronger.
cool, i guess the TPS does the same thing. That's the only sensor that the compushift uses right? The PCS and TCI controllers look like they use IAT and MAF and Tach to do the shifting, i like the simplicity of one sensor.the tv cable is what a 700 uses, correct? if so, 4l80 doesnt need it. i dont have mine running to tell on mileage.
