Title: 2002 2.6 Auto gearbox
Post by: coop1952 on 30 December 2011, 21:59:20
I'm having gearbox problems in that the box clunks into gears and when hot shudders and seems to missfire when pulling off. But these problems only seem to occur after about 5 miles or when the box has heated up. In the mornings or after the car has cooled down, it runs lovely and smooth. I believe there is an auto gearbox radiator to cool the fluid. Could it be that this radiator is not working and that the fluid is just overheating? After a long journey, there is often a smell, similar to burning rubber as well?

Need to check fluid in gearbox first really, do you have any leaks where you park your car from that area??

Could be auto box solenoids if you are getting a thud when gear changing

Never heard of a radiator for the cooling of auto box fluid

Auto's have generally had some sort of ATF cooler for years, my Dad's 1982 MKII Granada has its in the same place as most Omegas ie in the driver's side of the main radiator.

Is yours an Auto?

Its integral to the main cooling rad, ATF pipes connect in on the drivers side of the rad. There are ATF pipes at the top and bottom....

2.6 & 3.2 have separate coolers bolted to the cooling rad ;)

More cost cutting then, didn't know that. Never taken 2.6/3.2 rad out before only earlier V6's

Still on the drivers side? Must be?

Hummm quite different to earlier versions. Guess its cheaper to source one standard rad for all, then bolt that on when needed  :-\

Probably to give a better heat transfer rather than cost.

I knew later cars had a separate heat exchanger/rad hence me saying 'most'  ;)

Pre 2001 cars have the auto cooler in the drivers side of the rad - ie, in the cooler side of the coolant flow through radiator.

2001 on V6 have the auto cooler as a seperate rad, as pictured by RobG, that sits between the AC condenser and the main cooling rad, and is normally obvious by the pipes that go over the top of the main rad.

If these auto box pipes go into the cooling radiator how does the oil get cool when there is water or in there

To robG or Tunnie

The cooling tubes are separate, it does not mix the fluids with engine anti-freeze

The gearbox oil is hotter than the coolant and is reduced in temp to something like that of the coolant  :y :y and as said are two separate systems
