Suspect the above, on the 2.0. auto.  Revs go v high, car goes nowhere - feels like "clutch slip" in a manual.

Assuming the fluid level is OK - is it new gearbox time?

I think I know the answer...

I really do hate Omega autoboxes, they are the most unreliable hunks of crap autobox out there. The amount failing just recently is outrageous!

They may all be lasting a bit longer if they weren't "sealed for life" and have a dipstick for regular level checking / refilling

[sassanach]

[Dazzler]

Well as its a project omega.......could be a good time to find out how they work.....and take it apart and recondition  

As long as the oil isnt full of metal filings.......then id say its pretty much had it.

witchcraft is how they work- or badly got to agree with James all it needs is a dippstick and then there might be a chance of maintaining them

Well, my 03 2.6 auto is at 135,000, our 98 2.5 auto is at 235,000 and my previous 97 2.5 was at 200,000 when I moved it on.

They've only had fluid changes.

I do hope I don't get to regret this posting.

Fluid change would be dead easy if it could be drained with a plug, and refilled with the dipstick tube....

I have Marie's old sumps, with designs on welding in a couple of drain plug bosses.

Then again, if it's the first time it's been done in ages, a change of filter and clean out of the sumps is a good idea anyway.

It would be no problem to pop a drain plug in the sumps - just a PITA to do it on every Omega you need to do transmission work on
