After much inter web searching,.i find myself joining this group to pose my question..I can find no instance of anyone splicing into a 2.0 AT ECU in order to use the TC lockup on a Th180/ 3L30. Or more correctly,.to set the TCC relay..if cannot be done. Then it’s back to the Pull-a-Part yard for a 4spd.. This is a 1991 Tracker 4wd. I’m ok with the 3spd if the TC operates as designed for the 1.6..otherwise I’ll graft in the 4spd Aisin, mounts and driveshafts, speedo wiring etc.
Hello: Hangar5
not sure what car you have (when new and opted then) at all nor what modifications to (later) if done nor all problems related, you are experiencing. (sure TCC dead)
The old cars used a relay for TCC and then newer do not, the newer ECUs have Transistor direct drive. to to that. 1996 and newer did.
then you hint at 3speed and 4 speed transmission the latter are fully electronic shifted, but the former 3sp is only TCC electronics + full hyrdamatic.
are you saying you have 91 Tracker, 3speed now? and the TCC is dead, with 3speed ECU 1991? and if you hot wired the TCC relay ,output the TCC lockup fails. (or hotwire the TCC pin on 3sp box, TCC pin, its dead)
or how does a 2Liter ECU fit in here? confused. me.
the ecu must be marked A/T or it has no TCC controls at all, ours the tag shows, US-AT just above the partnumber, but ive no idea what ECU (PCM) you have. nor year.
