Oil Cooler Thermostat

will be running a cooler thermostat to maintain the transmission oil coolera or would I be better to buy a transmission coolera

1st 2nd question will not move to the second til 3500 RPMa it is because of thisa

Thermostat controls only the engine temperature, transmission temperature not. To cool the trans you need a transmission cooler. The offset is something out of my league.

transmission cooler is the way I think it go.but late.they too had many problems with it transmissions.
