Ford autotransission will not go into any gear. put in a used tranny and it ran fine for 2 wks now i have no gears

5 speed

is it still on the bench>????????
i rebuild many

1: the bearing in the front is bad.
2: the tranny is locked, bad shifter rail, detents
3: 4th gear is not a gear, it just locks themain shaft.
so if in 4th gear and input is jammed, that means
the cluster is jammed. if the cluster jams for any reason
it will be jammed in neutral. too, because the cluster always spins.
bottom counter shaft is called cluster. to old folks.

tell me , with the lid off tranny box.
did you test all gears, by moving the collars 1 by one.?????
each gear,? if not why not.????? never skip this step or fail big time.

then test all rail detents to make sure they all work(lid off)
and never allowing 2 gears selected at once (job1)????

then put in a new shifter sheet and try all gears on the garage floor,
all assembled!
then turn input by and and shift all gears on garage floor
i even use a huge drill motor to test tranny on floor, with tape on tip
of pilot shaft. and shift all gears,

this is all basics, , never just throw it together, do the tests.
as you go.

Turn on AC while idling, does engine speed increase? If not then replace Idle Air Control Valve.

Check for vacuum hose leaks

i have a 91 nissan max...it starts but it wont get the gears when i put it on drive it want to get it but doesnt run!..what can i do?help?asap

Take it back to the repair shop that did the work and have them fix it. If that was to fix the issue they are liable to fix it.

no the tranny aint going out you need tranny fluid in your torque converter

you need a different tranny because the reverse is a direct gear and is doent engage,the reverse doest work with the drive gear system,so you have a internal mechanical problem in you tranny

The trannys on the vw's are weird, they actually have a brain which tells the tranny what to do, when to switch gears under the driving conditions etc. Is thair a check engine light on? when is the last time you had a tranny service done on it? Also, it sounds even weirder, but is your alternator ok, is it putting out the proper volts to the battery? the alternator not charging the system can lead to alot of weird acting issues.

If you keep accelerating will it catch third or does it stay in 1st? Does it **** hard when you put it in gear?

my 96 mustang wont go into gears what must i do my is winston
