4spd Auto Trans servicing - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Tried asking this in other forums (fora?) but haven't had much in the way of responses - so here goes here...

I'm planning on buying an EB2 with about 200K kms on the clock.

Part of my usual 'new old car' process is to change all the fluids i can get my hands on.

My question is about the auto trans fluid.

1. Should i do a full flush or should i just drop the pan and replace what comes out of there - leaving behind 6-7 litres of old fluid?

2. From what i've read/heard, high KM auto trannies can fail after being flushed (something to do with removing old varnish off drive bands etc). Is this true?

3. Also, what exactly is involved in a trans service? the going rate around here is about $140-$150 - a bit hard to swallow if they're just dropping the pan, replacing the filter and topping up the fluid. I know which is the business end of a spanner - how much of a trans service (tightening bands, etc) is feasible to do at home?

Thanks

there is another method of changing all the oil. every night take out a bit of fluid from the trans via the dipstick. add the same amount back in. do this a few times and you will have essentially changed all the oil. never done it myself, i just dropped the pan. theres a kit you can buy with the pan gasket and the filter if i remember correctly.

You also need to adjust the bands as part of the service. I would do a full flush despite the theory about old trans varnish causing failure; if it is going fail it will soon anyway.

i agree with Aussiblue, do a complete oil change, its definitly worth it in the end, and if the box is goin to shit itself, it will anyway. I never adjusted the bands when i service my tranny?!?!?!?!

There is nothing to servicing the tranny, i am sure you could do it
