By using the TC do you mean pressing the button so the TC light is on on the dash?

Pressing the button so the dash TC light is on means the TC is turned OFF.

The burning smell will be your gearbox getting hot!  :o

Traction control is set as a default setting every time you turn the ignition off

is it normal for the gearbox to get hot?

Auto - yes

Manual - not really (it will get as hot as the engine on a long journey)

Traction control reduces the engine output when wheel spin is detected so that should reduce the load on the gearbox.

Which box do you have?

When T/C tells the ECU in an Omega to reduce power I assume it cuts a proportion the fuel injection cycles. It is unlikely to cut the spark without cutting the fuel because that would cause some spectucular backfires and shatter the cats.

Sooo. If fuel injection cycles are cut the cats/lambda sensors probably get lots of oxygen which may well make the cats smell a bit hot.

Thats my guess. I wonder if Kevin knows?

I'm curious. Does anyone know if my surmising is correct?

Will heavy use of T/C cause the cats to get unusually hot?

I'm thinking that Kevin Wood might be well placed to answer.

if your not using TC (ie the light is on) and your reving the nuts off it it would, everything would be getting hot but no air-flow to help keep things cool

That wasn't what I was asking.

I am wondering whether the increased proportion of air that (I think) ends up going to the cats when T/C cuts the power causes the cats to get unusually hot.
