Sump Plug

I own a 1994 Fairmont with a 4.0 6 cyl and a 4 speed auto
I have this problem, when ever Iam cruising at speeds above 60km/h and I back off the accelorator then go to accelorate again the auto seems to slip for a second or so, I can see the tacho go up an extra 500 rpm or so then it drops back when it grips. I went to the local tranny shop and straight away he suggested a rebuild, I'm very skeptical of what he said and when he told me the price I almost fell over backwards and died. My auto does need a service (the oil is a bit off colour )which will cost around $160 but I was just wondering if anyone else has had a similar problem and can suggest what the problem might be and how I could fix it. I just need a second opinion as I don't have a spare $2000 for a rebuild especially if it doesn't need it. Any help greatly appreciated

mine was slipping at one stage, but only when VERY cold (ie 4 degree morning 5 seconds after car was started) and was simply the trans fluid was a little low.

if you're going to get a trans service, get it fully flushed. costs a little more but its bettter to have all new fluid in there.

Mine used to "flare" between gears sometimes, a complete transmission fluid replacement cured it.

By the sounds of things, a service should do the trick ... the missus can stop fuming now :)

Sounds normal.From your description what happens is when you back off the lockup clutch drops out and when you accelerate again the revs flare slightly until the lockup comes back in..That's how it is supposed to work.
I don't think i would be getting a service done with that guy..Someone here should be able to point you to a good place for the service in your area.

SP,
Don't go back to that tranny shop, I think he's just looking for a bit of work.

I would still get the whole lot replaced, no point in replacing 3.8 litres when the sump holds 10, especiallly if the car has a few k's on it.

There are machines out there that can drain and replace the lot, don't know the cost. Castrol TQ 95.


cheers

When you say get the whole lot replaced do you mean the contents of the torque converter aswell?

No ,he is refering to the oil.Normally when the pan is dropped to replace the filter on a service only part of the oil is drained,in this case around 4 lts..That leaves approx 6 lts left in the trans and convertor..A flush removes all this so the oil ends up like new ,and the new oil then isn't instantly polluted with the old oil left behind.
