My 2006 Nissan Frontier leaked coolant into transmission…

My 2006 Nissan Frontier...

My 2006 Nissan Frontier leaked coolant into transmission cooler. The radiator was replaced and transmission flushed with new filter. Now the transmission slips and doesn't shift properly. can it be fixed without replacing the transmission?

Mechanic's Assistant: How old are the hoses? And have you tested the actual mix of your coolant?

The transmission fluid was just replaced and a new filter kit installed. Operates worse now than before.

Mechanic's Assistant: Are you fixing your Frontier yourself? What have you tried so far?

I am not fixing it myself up to this point. The transmission was flushed and a new filter kit installed

Hello my name is ***** ***** thank you for your question.

Normally once you have cross contamination in the transmission, the clutch pack material is jeopardized by the coolant. Which can cause shift issues, as well as it can cause issues with in the TCM ( which is part of the Valve body ).

So normally when you have the Trans cooler failure, the Transmission would need to be overhauled or replaced as well if flushing doesn't work I am afraid.
