this happen to anyone else? Over a year ago, i removed my auto ***** shifter and replaced it with an aftermarket one. when i did this, i also cut the 2 white O/D cables and left them like that since i never use it anyways.

I've never seen that OD light come on my dash UNTIL TODAY.

For a couple months now, i have noticed my tranny seems to have been slipping. Didnt think it had anything to do with it...until i saw this O/D light blinking like crazy today. Anybody have any idea why that O/D light all of a sudden is doing that?

 

from what ive heard the od blicks when you have a tranny issue.

I think you can check the codes on your o-d light the same as u can check your engine light----te1 to e-1


your tranny may be throwing a code

good luck

 

damn, i hope its not that bad. didn't really plan on doing an r154 swap until the End of the year.

 

When I had that O/D light flashing on my dash, It was because of a bad speed sensor...Hopefully, Your problem won't be anything major Good luck!

 

well the codes should help narrow it down-----hopefully it can be a simple fix and wont need to be swapped out entirely

good luck

 

thanks i'm gonna look into that too.

 

Nnooooo!!!!!!

Okay so your symptoms are:

Sludgy gear changes
OD off light flashing
Does the car go into overdrive at all??


Does the od off light flash straight away???
Or does it start flashing when car is warm...

What engine are you running?

 

well this happend to me before, i was cruising down the freeway, than halfway to my destination, my tranny stopped working. i pressed the gas and it just revved, mechanic said the tranny blew out. it was on my 92 sc400.

 

where is the transmision ecu located, is it mounted near the shifter mechanism?

i wanna switch my '92 tranny ecu with my other '97 tranny ecu and see if that makes a difference.

 

what do i us to check the codes?

I'm coming from an OBD2 world, and have never frolicked with OBD1

 

Vvti ecu will not work with old ecu.

But try it anyway.
Your trans ecu is ur main ecu.
Located in passenger footwell

 

ah there's no separate ecu for the tranny, cool. I actually replaced my ecu a while back, but just wondered if there was a separate module specifically for the tranny anyway.

I just dropped my car off at Toyota service to see if they can tell me wtf is going on.

 

did u ever find out what was wrong ?

 

Bad shift solenoid?

 

I'm actually trying to search methods of clearing all of these stupid issues with my r154 swap and came across this...My car does the same thing
