Its lost fluid so may well need a top up...but would gearbox selector problems cause this too or make things worse??

[TheBoy]

the symptoms are low atf

[MutantCav]

Ok, will give it a transfusion Thanks

Hopefully it hasn't pished out too much fluid and cooked the innards. Sump fluid will appear like mud and stink if this has happened.

Be worried if it takes more than a litre to top up, although you may be OK if it hasn't been driven too hard.

Stating the obvious, it would be prudent to find the source of the leak and keep an eye to it.

My money's on the torque converter seal, which hardens with age and high mileage.

Not much worse a job than changing the clutch on a manual, as it lives external to the front of the autobox and is easily accessible once the converter is removed.

The seal cost me about £17 from Autovaux and is held in place by three small bolts. The new one needs to be tapped in to its housing gently with a block of wood to protect it from damage.

It's nice not having the smell of burning oil wafting up from the exhaust any more...

Is this from cold, if it is then it is quite normall untill cats warmup.

[MutantCav]

Ok sorted...litre of fluid and all is well...with the box anyway lol

Changing quickly and cleanly now...not a leak but the fact that I cut the pipes from the pump to the box in preparation to strip the engine out then started the engine forgetting I had...then had to fix the pipes due to no longer stripping it!

Thanks for the help, you are as always spot on with analysis guys

Did you flush, top up or turkey baste your system??

[humbucker]

is there a way of telling if your autobox fluid is low? i take it doesnt appear on the mid?

[MutantCav]

Dont know mate, but there was a distinctly pregnant pause between putting it in drive or reverse and it actually going into gear to move the car...litre of fluid sorted it perfectly First time I have topped up a box and was so surprisingly easy to do...

Plus got the GM Motors DIII gearbox fluid from Halfrauds...sorted!

If you drive with the big pause too long, the box may be toast soon...

how long are we talking then, between gear change and getting into gear? just for future reference...

Virtually instantaeous.

i meant the pause, but i guess from your response you mean ANY delay is a bad thing?

There should be virtually no pause - by the time you drop it in to D, you should start to feel the drag.

My 3.2 V6 it takes a few seconds before fully engaging if the cars has been left stadning for a while (say 2 days).  Via Autobahnstormers I've heard that this is not unusual.

I can't check my autotrans fluid easily (if at all), I did change it and the filter at 50Kmiles (now about 75k miles).  the fluid came out clean.

Hope this help
