.? Transmission.

[Scott1212]

Did GM put out a bulletin on changing the thermostat to make the transmission run cooler ,and shift better ? Didn’t know if it was a recall ,or Just a Tsb  bulletin if you were having issues with how the transmission was operating not correctly in order for them to complete the process to switch it out with a new one .any info would be awesome thanks again Scott !

It wasn't a recall, but a service bulletin.....

Thanks for the info..I’ll have to make an appointment,truck is still under warranty,transmission acts sludges when hot after driving on highway towing a boat ,I’m guess a lower temperature thermostat may help prolong my transmission life and shifting concerns,probably should’ve been a recall all the transmission issues they have ,then again that would be costly I’m sure .
