Hi My 2003 Toyota rav 4 autiomatic model has some shifting problem while driving especially in slow speed.The gear not shifting smoothly instead that it makes some sounds and then only it shift with a jerking mood.Some times when we press acceleration instead of moving it act as in neutral position ,means only raising sound but not moving speed. Please advice me the real problem Thanks Vincent

Probably shift interlock solenoid.

Not likely to be the clutch pack as you dont mention slipping wich is the normal sign of overheated or worn clutch bands.Not sure with your vehicle but 2 methods that control the shift severity are engine vacuum or pump pressure inside the auto. so check balls are a possibility. They are spring loaded to open at a set pressure,or close.Could you check to see if its a vacuum controled and if so its a lot easier to fix as the vacuum control should be outside the trans.

I work for Toyota, and I will be glad to provide you with the actual answer:

The RAV/4 product is available in two models, a 4WD model and a 2WD model.
The difference between the two is on the 2WD model, there is no driveshaft going under the vehicle to the rear wheels, and no rear differential. There is no "RAV/2"; both models are called RAV/4's.

There is a lot of common confusuion about how the 4WD works. It is full time 4WD. In other words, it is always in 4WD. It does not "kick in/kick out/automatically engage", or anything like that. It is 4WD all of the time. But, when I say "4WD", that is sometimes mistaken for "all wheel drive", and, in this case, the RAV/4 is not "AWD". What this means is that if you raise the RAV/4 up on a lift, and put it in gear, 1 rear and the other side front tires will spin. True "all wheel drive" would have ALL 4 wheels spinning. This is not the case with the Rav/4. What the RAV does have, making up for not having "True AWD" on the 5 speed model, however, is a switch that locks the center differential in the transfer case, which, when engaged, applies a method of "locking" the 4WD system for maximum traction, but it is still not AWD. The automatic version doe not have this ability.
The last "true AWD" vehicle for purchase was a 1970's International Scout.
If you are considering purchasing a RAV/4, that is a very good investement. They hold their value quite well, and are virtually bulletproof; I do not make any "money" off my RAV/4 customers...
Just "gas station work". Very nice cars. I hope that this helps you, please feel free to comment back with any otherr questions...Glad to be of assistance.

I would suggest hat you replace the timing belt. The noise that you hear is the belt.

I had the same problem with my 1991 sv21 camry, it sounds like the reverse clutch is on its way. if you try to engine brake the car in 2nd or low gear does it hold, or slip?, if it slips then the box needs to come out and the cluch replaced, or is the fluid low? i had spent around $1500 Australian Dollars to fix the issue but with the 5sfe enging im aware that the whole engine and box assem, has to come out as well.
