I'm searching for an alternative GM 180 thermostat? I've researched the reviews on Jet, and other aftermarket low temperature thermostats and ALL seem to have a very low rating, poor gasket design or material prone to premature failure. I've seen the GM 197 degree part # 12674634 I really prefer a lower thermostat is anyone is aware of a GM OEM . Thanks

Hello, I happened across your post and am planning my own installation of an auxiliary transmission filter. I do have questions? Is there any data regarding flow restriction/constriction on the return fluid that could prove detrimental? Secondly, from the posts it was mentioned using rubber hoses with barbed connections. Can I assume the pressures at the INLET & RETURN are low pressure? My filter says not to exceed 90 psi. Thanks again.
