1990 Previa 2.4 Automatic

[chillihippy]

can anyone help? i have a 1990 previa 2.4 automatic that doesnt want to retain its transmition fluid, i think its the input shaft seal, but i cant find any information on these gearboxes nor a haynes manual to see how i go about removing the gearbox to repair the problem, this is the only fault i have with the car, mind you i have only owned it for two weeks. ant help would be greatly appreciated, the leek appears to be between the engine and gearbox xxx

I'm sorry I can't help. Haven't had this problem - although do have a leaking rocker cover gasket. These engines are heavy lumps so take care.

you wont get a haynes and the engine manual doesnt describe the gearbox - best bet if its not already fixed is to speak to bob at rcmvr.co.uk
