My 85 Topaz auto is doing the same thing...in a 'phone diagnostic
discussion w/a transmission specialist, he suggested the most
likely culprit to be a governor either on or in the tranny, which
operates by hydraulic pressure to change gears at certain speeds
and RPMs. Apparently I'll have to have it repaired. However, I'm
going to change the fluid first, to see if that has any effect. As of
this date, 3-8-'10, the repair estimate is in the $300 ballpark.
Check the fuses, if fuses are okay, it is probably the VSS (Vehicle Speed Sensor) or wiring to it at fault.
Battery + cable goes to one of the large posts Starter cable goes to the other Large post Trigger wire goes to the small post (if there are 2 disregard 2nd)
Low transmission fluid, transmission on it's way out.
It's below the gear selector lock button on the automatic transmission cosole shift
The switching is done within the transmission by internal pressure. YOu may just be low on fluid. I have had this happen to my 93 topaz three times (plus a fourth that happened before I got the car). Every time it happened the fluid level was full. The tranny used (ATX) on the topaz has a governor on it. If the governor is not set right it will not shift. I have had to have the governor gear replaced Dec. 2005 because of this. Once you have one problem with the transmission you may have problems the rest of the car's life. I am now on my 4th transmission.
You can't shift gears on an automatic transmission because, as it is called, it's automatic! You don't need to shift, it does it for you. == == Maybe the question should be "Why is my automatic transmission not shifting through gears for me as it should?" Could it be a fairly simlpe fix or am I losing my transmission? Yeah Dopey!
It can come with either one. But the standard is an automatic transmission.
Not if you have an automatic transmission.
electronic solenoid
An automatic transmission shift valve is like a swing. It is moves back and forth with the use of pressure. That is how gears are changed.
An automatic transmission modulator is the device that decides when your vehicle should shift. It basically controls and regulates pressure for smooth operation of the automatic transmission.
Shift solenoids are inside the transmission.
