tranny fluid in coolant

On my way back from work last night, my transmission acted very stange. It slipped in first gear and it seemed like the truck had no power when taking off. When I got home I noticed that tranny fluid was comming out from the coolant plastic reservoir and I also noticed some fluid on the driveway from the night before. I had the truck towed to a garage this morning but they have not looked at it yet. I hope I did not damage the tranny because of low fluid.

Re: tranny fluid in coolant

You have a ruptured transmission fluid cooler line in the radiator. Time for a new radiator. Drain and flush the transmission and engine cooling system.

Re: tranny fluid in coolant

I replaced the radiator, flushed both transmission and engine cooling system and I am running again. (Costly job)
Thank you for your input.
I have another question.
Last spring (april 2006), I had Check Engine Light on and it turned out to be P0171. I cleaned the MAF sensor and it did not come back until May 07. This time I disconnected the baterry and it has not come back until yesterday(same code P0171). Any suggestions?

A search of the forums would show both this thread:

and one in the FAQ of a more general nature pertaining to trouble codes.

The short answer is that you most likely have to replace the MAF sensor ($160) or possibly the ECT sensor.
