My transmission does not engage when cold, but once its warmed up, it works fine. Transmission fluid level is good.
If I rev the engine high, it allows the transmission to engage even when its cold. I tend to do this in neutral, then shift into Drive after the high rev. Sometimes this leads to transmission jerking into gear.
If I don't take my foot off the gas, the trans stays engaged. If I drive for 2-3 minutes without stopping, symptoms go away completely. I assume this is because the transmission fluid is warmed up and free to flow. This leads me to suspect it might be the transmission filter not allowing fluid to flow freely? Or perhaps it is something else?
This transmission has exhibited these symptoms since first being installed in June of 2012. Its a Manny Tranny.
I'm worried that I am damaging the transmission when I need to rev the engine high to make the transmission suddenly engage.
Any feedback is greatly appreciated! Thanks,
