Likely it hasn't been serviced in a long time. I'd try changing the fluid and checking to see what's in the pan. If filter is plugged up and there is an extrodinary amount of metal or clutch material in there you may need to replace unit (some debris is normal). If fluid change helps, do it again in about 1500 miles. When you drop the pan, you have changed only about half of what's in there. A good additive may also help... I've used one made by Lucas from time to time and it has actually helped, when the unit was gummed jup but not internally worn out.Don't expect anything to remove problem overnight, it took a long time for varnish inside unit to get there!

I have two toyota pickup truck 89 and 94 with 22re engine, I swap the engine the 94 manual transmission is ok but the 89 automatic transmission is not shifting into 3rd gear and the check engine comes


welcome to modern cars, the newer cars have a TCM.
you can just swap a mech, trans for a electronically swifted trans.
I swapped, you meant.
its not clear what you are doing here,.
why are you swapping engines
and are you expecting both cars to run? which makes above line odd.
no?

Transmission does not shift automatically, only manually. Swap in a known-good PCM, check wiring, check other sensors such as VSS and TPS.

Trans shifts into gear harshly, car feels sluggish off the line
, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmision is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the underhood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.

Car goes into gear but feels very sluggish like the brakes are dragging, but it will roll easily (starts out in 4th gear), you manually shift to 2 to get it moving, once it's moving you put it back in OD and the car shifts 3rd to 4th on its own and locks the converter at the appropriate time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Good luck and get back to me, hope this helps.

It needs some work to be done in gearbox, worn selector detent ball or weak spring.
