Thank you for using just answer.

This is a common problem on your truck, did the dealer have any other inspections or repairs other then what you mentioned above? How many miles on the vehicle?

Customer: replied 4 years ago.
all they did was exchange fluid throught the dipstick with a machine that circulates old fluid with new fluid. My third gear shifts hard and sometimes the tach jumps from 3000 to 3500 and then shifts. I took the truck to autozone and this is what the actron code read Shift Solenoid B Circuit Malfunction . Is this a pressure switch inside the the transmision or a electronic sensor on the outside which is a cheap fix or am I going to face a rebuild?
Expert:  Toyotapro replied 4 years ago.
Not a transmission issue here, I need you to answer all my questions so I can best help you, how many miles are on this vehicle?
Customer: replied 4 years ago.

276000 mainly highway miles. I drive 140 mile round trip to work and home daily

 

Expert:  Toyotapro replied 4 years ago.

ok, high mileage and definately out of warranty.

Are you familiar with the engine computer on your vehicle and it's location?

Customer: replied 4 years ago.

My friend might find it. I do not know it location

 

Expert:  Toyotapro replied 4 years ago.

Reason I ask is because there is a "known" issue on your vehicle with this code, this condition and this symptom. The issue is inside the engine control module and causes this malfunction, the part # XXXXX the ECU needs to be checked to see if it has the updated ECM or one of the old part #'s that is known for this. If the ECM is the wrong # XXXXX this is step #1 to replace.

These are all the old part #'s that are possibly on the ECM:

89661-42650

89661-42651

89661-42652

89661-42653

89661-42660

89661-42661

89661-42662

89661-42663

89661-42810

89661-42811

89661-42820

89661-42821

89661-42880

89661-42890

If any of these are on the computer then this is the old part #.

Yes with this kind of mileage on your transmission then there is also a possible issue inside the transmission but the computer needs to be addressed first.
