Assuming there isn't transmission damage, you probably have a kickdown cable. It's a cable that gets pulled on when you press the gas. It takes into account how hard your gas pedal is down, and delays shifting the closer you are to WOT. (wide open throttle) Perhaps it is a little too tight. Becareful though - if it's not the problem and you move the kickdown cable, you can damage the tranny if you make it shift too hard. So make sure you scribe a mark or something before you even touch it so you know where it was originally. There will likely be a bracket of sorts that allows minor adjustment.
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.
It sounds like there may be an issue with the throttle linkage adjustment or the throttle cable itself. Check to make sure the throttle cable is properly adjusted and that there is no binding in the linkage. Additionally, ensure that the carburetor is set up correctly for your specific engine and transmission combination. If the issue persists, consult a mechanic for further diagnosis and adjustment.
YES Some were all wheel drive. Allthough both front & rear are limited slip, & the rear only if the front wheels are spinning.
To install an alternator on a 1993 Mercury Topaz, first disconnect the battery and locate the alternator. Remove the drive belt, unplug the electrical connections, and remove the mounting bolts. Install the new alternator in the reverse order, making sure all connections are secure before reconnecting the battery.
The 1991 Mercury Topaz has a fuel tank capacity of around 13.5 gallons.
If it is the same engine, both either standard or auto, might have to check if the 1990 had over drive, cause the 88 or most of them did not.
Check the fuses, if fuses are okay, it is probably the VSS (Vehicle Speed Sensor) or wiring to it at fault.
and the question is?

If a Mercury Topaz is revving while driving without shifting, it could indicate a problem with the transmission. Possible issues include low transmission fluid levels, a failing transmission, or a malfunctioning shift solenoid. Additionally, a faulty throttle position sensor or other engine-related issues could also affect shifting. It's advisable to have the vehicle diagnosed by a professional mechanic to identify and address the underlying problem.
Have to remove the transmission for that.
There isn't a transmission capacity the only thing you go by is the amount of gears it has.

Possibly. Look at the model # on each transmission. If they are the same, then they are interchangeable.
It could be a warped clutch disk, a faulty pressure plate, poor adjustment or air in the hydraulic clutch line. If it shifts somewhat normal when the engine is off it's a clutch problem.
Dexron 3 will do just fine.
the first step that should be taken is to have the transmission serviced, this should include removing transmission pan, draining fluid, removing and replacing filter and pan gasket. then if the problem persists it would be best to have the vehicles computer scanned to see if any problems are present with the transmission. usually the computer will store fault codes which will help pinpoint the problem.
