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.
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.
Transmission shift linkage installed incorrectly or out of adjustment.
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?
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.
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.
the swwitch is on top of the transmission
it depends on whether your car is automatic or manual shift.
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.

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.
If you don't see one on the trans pan, it does not have one. Pan must be removed.

The 1993 Mercury manual transmission linkage will have adjustment nuts on each end of the linkage. Turning the adjustment nuts will move the linkage back in forth.
Big job. You have a choice, remove the whole engine with the transmission, or just the transmission. Either way you have to be equipped with the right tools. Best is to find someone to do the job for you. It will cost.
Usally left side in front of transmission if not follow battery cable wire
When white topaz is irradiated, it will change to pink or different shades of blue. The form of radiation will cause it to be a different shade.?æ
