Auto Transmission

[ugy]

Hi guys,

I wonder if someone can help me out here.

I realize that stalling up will overheat the trans and was wondering if I had a long break between runs(eg..half an hour) if it would help a lot.Also is there anything else that you can do to help keep the heat down. I am looking to get a tranny cooler soon so was looking for some advice in the mean time.

Thanks Bill

If the oil is to cold it can be just as bad as too hot!

The new ZF has an Oil cooler with a thermostat to bring the transmission to operating temperature ASAP.

The secret is to try and keep it as close to operating temperature as possible for optimum performance. Simply not too cold and not too hot.

Bigger coolers are not the answer as some would expect unless they are controlled in some way to try and maintain a close to constant temperature.

The STD type oil cooler simply relies on the resistance to flow of the internal tubes and as the oil gets hotter and thinner it travels faster through the core which intern allows a greater volume of oil to be cooled (If it has a Bypass valve)

If you have this system then all you need is a cooler with the capacity to cool in the worst type of situation. I.e. stalling for long periods of time.

First you need to know what sort of system you have or wish to upgrade to.

So many different ways and types to choose from.

Thanks for that

Great answer

What effect would a higher rpm stall convertor have?

PS Hi Ugy!
