Shane Posted December 27, 2010 Share Posted December 27, 2010 Does anyone know what form the stock transmission cooler takes inside the radiator? Is it as simple as it looks and just a single piece of tube that sits in the bottom tank of the radiator, or is it more complex than that?

Swampy442 Posted December 27, 2010 Share Posted December 27, 2010 Nothing spectacular, its just a small section of the bottom of the rad. Quote Link to comment Share on other sites More sharing options...
Shane Posted December 27, 2010 Author Share Posted December 27, 2010 Nothing spectacular, its just a small section of the bottom of the rad. OK thanks. I didn't realise it had it's own section and presumed it was just the pipe passing through the lower section. how small a section is it? So would I be right in thinking that the transmission fluid gets hot before the coolant and relies on the coolant in the rad to cool it and then as the engine warms up everything evens out to the running temperature of the engine? i.e. both coolant and transmission fluid are the same temperature?

Swampy442 Posted December 27, 2010 Share Posted December 27, 2010 Looks like you were right, its a tube in the bottom section of the rad. Ive no idea what the operating temp of the gearbox is but youre idea makes sense. Quote Link to comment Share on other sites More sharing options...

No I think the coolant warms up the fastest , it in turn warms the transmission fluid , up to the point the trans fluid runs hotter than the coolant then the coolant helps cool the tranny fluid Quote Link to comment Share on other sites More sharing options...

Thanks again. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 28, 2010 Share Posted December 28, 2010 The wife's Stagea wouldn't drop into lock up mode in the very cold recent weather, unt5il the transmission oil temp had risen a bit. I found it has a temp sender that keeps the converter from locking up below X degrees. The transmission cooler in the bottom of the rad works as a transmission warmer at the start of the warm up cycle, as does the engine oil to water heat exchanger on the engine block.
