1993 Rodeo Transmission Check Light Fashing

:banghead: When you first start it, you can drive it for five miles or so and it drives fine. Then the check tranny light comes on and it goes into limp mode. When I turn it off and restart it, the light will stay off as long as you put it in reverse, low 1 or 2. The other two gears feel like it is in winter mode. I have looked at other posts but cant figure it out. I have replaced the alternator with another used one that was tested before installation. If there is anyone that could help me figure my problem out, I gladly accept the advice and thank you in advance.:crying:

When was your last transmission service? How many miles? Have you checked your transmission fluid level?

is the alternator putting out more than 14.0 volts?

New OEM alternators are your best bet. I have only heard of one instance of someone putting in a remanufactured alt and having it work.

now you've heard of 2. . .or. . .3:

my first choice: rebuilt by bosch. no problems. good, but not cheap, price.

actually no problems either from the rebuilt sold by the dealer -- except power steering fluid messed it up. also good, but not cheap by a long shot, price.

Ok!
