The wheel bearings for the Mercury Topaz are found on each axle. The average cost for a set of bearings is about 70 dollars.
Only the 2.3L HSC Inline 4 will fit in the 1986 Mercury Topaz. If everything in the engine bay were gutted, perhaps something larger such as a 3.0L V6 from a 1992-1994 model MIGHT fit but it would require a complete running 92-94 Ford Tempo or Mercury Topaz with the V6 engine as a donor car (and, if you could find such a car, it would be more worth your time/money to invest in it v.s. a 1986 model). The automatic transmission from a Taurus WILL NOT WORK in a Tempo/Topaz.
There isn't a transmission capacity the only thing you go by is the amount of gears it has.
Dexron 3 will do just fine.
Possibly. Look at the model # on each transmission. If they are the same, then they are interchangeable.
Need more info.
Mercury Topaz was created in 1983.
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.

To instal a neutral switch on the 1991 Topaz, kindly make reference to your users manual.
On my 1993 Topaz, the transmission fluid dipstick is on the right side of the engine, near the front, just to the left of the battery. It looks a lot like the oil dipstick, but, when you pull it out, the writing on the dipstick clearly mentions that the fluid level should be checked when the engine is hot and idling, and that a certain type of Mercury automatic transmission fluid should be used to refill.
Low on fluid, dirty filter, worn clutches.
