where is the turbine speed sensor
I have a 1992 Geo Metro automatic. and it does not shift, I have to manually shift it...I have changed the transmission module under the dash, the two shifting solenoids in the tranny and now I hear it may be the turbine speed sensor located on the tranny. Does anyone know where it is on the tranny?
 How about where do you get one?

Re: where is the turbine speed sensor
it is on top of the tranmission. held in with the 10mm bolt, has 2 wires going into one plug, its black. once you get it out its easy to test its just a coil of wire wrapped around a iron core. if it has continuity its good, if its open its bad

Re: where is the turbine speed sensor
I've never heard of such a thing. There is a vehicle speed sensor plugged into the top of the tranny that has already been described by Crvett69.
You can go on replacing things that you"heard it might be" until you have an entirely new car that won't shift, or you can buy a proper manual and troubleshoot the problem.

Re: where is the turbine speed sensor
I can consider this 92 Geo Metro as a hobby...fun to work with...so messing around with things and trying to fix stuff is fun to me. I have a manual...it doesn't talk much about the tranny, nor does it mention speed sensors...

Re: where is the turbine speed sensor
That came across as unnecessarily mean of me, sorry. Here's a link to a troubleshooting guide, don't know how good it is, just the first thing I found: http://www.teamswift.net/viewtopic.php?f=9&t=35213 I think more reading about at TeamSwift will get you more info, your failure is not rare.
Seems to me, if it shifts fine manually, it has to be the controller, solenoids, or the wiring in between. Taking my advice on an automatic transmission is not the best way to go, I've only owned one in my entire life and that was 40 years ago.

Re: where is the turbine speed sensor
i had one that would start out in second gear and sort of shift into 3rd halfway, was acting really weird. if i unplugged the transmission computer i could shift it manually. the speed sensor on top of the transmission was open, replaced it and now it shifts and drives fine. like i said, test yours with a ohm meter
