DaveT Posted January 8, 2018 Share Posted January 8, 2018 There is no electronic control of this transmission. It's all controlled by hydraulics. Quote Link to comment Share on other sites More sharing options...
john in KY Posted January 8, 2018 Share Posted January 8, 2018 Check the modulator vacuum line. May be disconnected at the engine. No vacuum, no upshift. Quote Link to comment Share on other sites More sharing options...
Gloyale Posted January 8, 2018 Share Posted January 8, 2018 Check the modulator vacuum line. May be disconnected at the engine. No vacuum, no upshift. the governor is what controls upshifts. if you replaced it and it still not shifting, then the gear on the output shaft that drives the governor is toasted. trans is shot.

DaveT Posted January 8, 2018 Share Posted January 8, 2018 Yes, governor and that vacuum modulator. That's it, except for internal failure. Modulator should be number 1 thing to check. If it's original, it should have failed by now. Quote Link to comment Share on other sites More sharing options...
jono Posted January 8, 2018 Share Posted January 8, 2018 (edited) Has a basic look been done to it for starters before leaping into harder things, like pan off, inspect and replace filter and fluid. A number of bung plugs on the side can be opened and hooked up for pressure tests - have you any fluid pressure gauges etc Have to admit I got a from you looking for the 3 speeds TCM Lucky I didnt answer first as I might have suggested you follow the wiring connections from the trans to find the module :)I Edited January 8, 2018 by jono Quote Link to comment Share on other sites More sharing options...

DaveT Posted January 10, 2018 Share Posted January 10, 2018 That is the engine control unit. The list of codes has been posted in many threads. Count the slow blinks, and the fast blinks as a 2 digit number. Post them, and we can look them up. Slow is 10s place. Fast is 1s place.
