[Gmecm] introduction, and 4L80E questions...

[mike reeh]

Hello I just subscribed to this forum.. been lurking for many years, off and on, now I have a real reason to subscribe and enter the discussions....
   
  heres my scenario: Im putting together a project truck ('77 GMC K25) with a 4L80E trans... I got the trans from a '91 suburban, and I also got the factory ECM for the same vehicle.. Has anybody used this stock ecm to control JUST the transmission control function? I will not be using the TBI or anything else, Im only interested in controlling the 4L80E and possibly having some means by which to modify shift points, TCC, etc...
   
  I already bought a TCI standalone controller- BUT Im still very interested in using this GM ecm. I can always get my $500 back out of the TCI box, if I can get the stock ECM to work here... It will be a couple of months before I put the transmission into the truck, so time is what I have.. Any ideas? 
   
  thanks,
  mike reeh
