The original 89661-60250 ecu was damaged and replaced. I cant find same part number and the ecu was replace with 89661-3D100. The engine runs well up to 80 kph (looks like up to 3rd gear only) but will not shift to higher speed. The engine revs fine even at 4000 rpm. What could be the problem? Can any adjustment or setting needed? Thanks.

At best as I know the 2005 Prado is all time 4WD vehicle.
Is the engine running ? Can you shift the gears ?
May be something is broken in the drive train...
As a suggestion you can go home by locking the centre differential, proceeding at low speed and checking for noises .
Pls. let me know if it helps...
Normally Shifting out of gear in motion wont damage much unless you revved the engine really high for an extended period. Shifting into park while in motion will make a ratcheting sound, but usually wont hurt anything. However the act of doing so may have tripped a fault in the ECU that makes the car think it needs to be in limp mode. It did just that and got you home albeit running roughly.
Have someone remove the NEGATIVE battery cable. leave it disconnected for a few minutes, then reconnect and jump start the car if the battery is too low. doing so should reset the ECU and restore normal operation. If drivable, proceed to a brand name parts store. they usually will reset your ECU codes for free. IF all is well this should fix the probelm. If something was indeed damaged, you wont likely be able to drive the car.
If it is a standard/manual shift transmission, the clutch slave or master cylinder is probably going bad. If you continue to drive it like this it can damage the transmission. I would get these parts checked out ASAP to prevent transmission damage. This is a minor repair compared to replacing the transmission.
If it is an automatic transmission grinding and not shifting, the problem will be inside the transmission itself, and it should be repaired or replaced.
sounds like two problems 1 engine can idle high with vaccum leaks or bad idle air control or maf sensor 2 if trans wont shift in to gear fluid first next would be to tcm or wire connection on trans good luck
You either have a bad engine coolant temp sensor & connector.Located under upper radiator hose at cylinder head Yellow & black wire.Original sensor is ceramic & replacement will be brass from saturn.Also you may check for vacuum leaks at PCV hose & valve.Hope this helps
well i would try replaceing that sensor first it is a speed sensor and it has a lot to do with the shifting of that tranny if it dose not work yea with what you have exsplained it is probly time for a tranny but this fix is worth a try thanks kdc744
