Post subject:  Auto gearbox condition???

I am so excited, I just picked up my new 1997 JLX Vitara. It's auto with the J20 engine and has a 70lt fuel tank from factory! It is in excellent condition and has done 215000km's.
The only thing I need to ask is it normal for the gearbox to be clunky when going from park into gear and shifts a bit clunky? Can these autos be served and repaired sucessfully if need be?
Any knowledgeable answers appreciated.

Depends on how quickly it's shifting. If it shifts quick that's fine. if it's slow, especially from D to R, then that's a sign of wear. Transmission is an AW-4 and is generally very durable.

It's possible the clunk isn't from the auto at all but is from a worn rear A arm ball joint or worn uni joints.

Thanks. It clunks going from park to drive/reverse. Shifts ok whilst driving. Sometimes a little lag. Will check the joint and uni's.

My guess is the kickdown cable is sticking, this controls the line pressure in the trans, it's a common fault.
Try unhooking the cable from the throttle then shift between D N R to see if it improves.

Aw4 doesnt use a kickdown cable.

It most certainly does - although I believe it's now called the TV (throttle valve) cable.

I was going to say mine does too.

Im pretty sure mine has a vacuum actuator valve not a kickdown cable ?

Call it what you want. It's the cable from the AW4 trans to the throttle body, it sometimes gets stuck & causes the problem the OP has described.
