Would a Transmission Cooler Help a Vehicle that Stops Shifting After It Gets Warmed Up

Published 08/05/2015

Question:

If I install the supplemental transmission cooler myself will this fix the problem of my car not shifting on freeway and losing power. It is no longer under warranty I am at 132000 miles and they want to charge me 1000.00

Sounds like your transmission is losing line pressure after driving it for a little bit and then stops working. I have had two transmissions do the exact same thing as what you described and the first time it required the transmission to be rebuilt and the second time I had to install a new torque converter.

It's not that your vehicle is getting hot that is preventing the transmission from working. The problem is that there is a ton of junk in your fluid that ends up clogging the pickup of the transmission and makes prevents the vehicle from shifting/moving. Once you stop the pickup gets partially cleared and will work for a little while longer.

Once you get a new transmission a cooler like the part # D13502 would do an excellent job prolonging the life of it.
