My 88 2500 k pickup not shifting into 3rd or 4th

Corrupt adaptive shift memory. Try clear and relearn.

You more than likely need to have the transmission overhauled

If it grinds when trying to shift, it is the synchronizers. Rebuild. If it pops out of gear. there is a plastic part at the top of the transmission that wears out. It fits around the ball of the shifter. It is two pieces. You'll have to remove the floor plate and pull it up to access the bolts to remove the shifter and replace those plastic pieces.

05 Chrysler pacifica is a 4 speed automatic, next time buy a car with a 5 speed automatic

Check the transmission computer

Does that transmission have external shift linkage? Sounds like a linkage broke or the neutral gate is way off.

possible selector linkage adjustment , loose or shifted

Hi:

Your transmission has 3 shift rails...
1st - 2nd
3rd -4th
5th- Reverse

If your 3rd gear doesn't work , you have an internal transmission problem, such as a syncronizer, or similar fail... There is not much you can fix, without removeing the transmission.

you have a valve body problem, some of the speed sonsor controls are malfunctioning... need to get into the valve body... check fluid condition for dirty and burned condition...

Hi All

I have a s40 1.9d / 2000 plate,
In the last month or so the car loses revs when changing up to 3rd and 4th gear, I can only get 50 mph max in 3rd gear 80mp in 4th.
The car has just clocked 185,000 miles
Its a great car but a pai at the moment, I've had a service including fuel fillter change added fuel cleaners to the deilsel all to no avail


Any suggestions
