A340 no 4th gear

2003 tacoma 4x4 auto trans

Recently had ball joint failure going down the road. Shop warrantied ball joints and ended up putting a hole in my radiator while trying to move the truck without the wheel. Replaced radiator and refilled trans and coolant.

starter went out while it was at the shop and I did not trust them to do it so I hauled it back home and changed it myself. Went to drive it and trans was not shifting right. I have 1-2-3 but now 4. Shifts are off revs a little higher than normal. When in 3rd I can’t go faster than 25mph at around 4-4.5k rpm.

Drained as much fluid as I could and it was pretty burnt. Replaced fluid with dex III i believe and didn’t fix anything. Took trans pan off and changed filter. New filter and oil still no change. Where should I start? Solenoid? Valve body? Whole trans?

 

Are you a 4x4. Sounds like you are in 4lo.

 

Most trans cant survive the ATF being flooded with coolant. It sounds like you've done what you can. Shy of a tear down with new parts in hand there's not much you can do.

 

Always check that kick down cable coming of the TB....if its disturbed/binded or out of adjustment, shifting gets wacky

 

Time for a manual swap
