Engine sound cold

[91babyblue]

Thx for reply yes. Only thing now. When I plug it in and block is warm it doesn’t n m she that churning sound . Would plugging truck block heater prevent torque converter sound?

It could be conducting enough heat to warm the TC just enough to thin the fluid. Another thought could be pressure relief valve in the engine oil pump.

When was the last time the trans was serviced? does it has the correct fluid? It is possible that the filter is partially plugged and the fluid is a bit thick due to the temp and that MIGHT be the cause of your sound.

Could be the oil pump itself. On a cold start it is practically churning butter.
