There are a couple of reasons why a 1993 Mercury Villager is hard to shift. One reason could be a gear shift cable. Another reason could be low Transmission Fluid.
too low trans flid
That's hard to answer, since I don't know what a "calistar" is.
It is inside the dashboard towards the center at the very back. It is VERY hard to get to.
It is under the intake manifold. Darn hard to get to and expensive to change.
older villagers have a problem with the transaxles valve body which causes a hard second gear-there are aftermarket shift kits that remedy this problem,needing to be installed by a competent transmission shop.I have been rebuilding ford automatics for twenty years and have seen this problem several times-used to have to buy a different valve body because of premature wear on shift valve bores,but the shift kits repair the problem rather well.contact your transmission specialist before it damages the 2-4 band or breaks hard parts.
you have to put your foot on the break pedal, to shift out of park its a safety feature
The ball joints on a Villager are actually easy, just bolt on parts, the only hard part might be getting the stud separated from the knuckle, but if you're replacing them just use a wedge and it should be easy.
This is a custom bent tube with flared ends. It would be hard to duplicate. I believe it's a 1" tube.
yes it comes with hard top a toneau top and soft top.
it's probably not, check your distributor, i had similar problems, changed regulator, fuel pump, car still would stall or hard start. it turned out to be my distributor. i will repeat, this is a problem with the villager, they go bad quick.
The TPS is located on the back side of the throttle body. Like all other sensors on the Villager, hard to see, almost impossible to get at to replace. I would suggest obtaining a repair manual at your local parts store.
Generally, one should have the codes scanned to make sure all the sensors are working correctly. Out of spec sensors can cause damage to the transmission. Make sure the alternator / battery voltage is correct too as I've had hard shifts when my alternator died. Failing that, you'll need to have a transmission shop check it out, working on external checks first before tearing it down.
