Trans shifts AWESOME now!
by Jerry/Betty Sutherland -
2012 Ram Megacab totally stock. 109k miles. Started overheating the trans on his way from So Calif to Boise.
Got up to 220 degrees at one point.
So after installing the ATS Valve body it shift awesome. Had a little bit of high line pressure but we didn’t see that again after we did the thermal bypass delete on it.
I’m still in disbelief on all the crap I found on this truck. Especially since I had it in my head that the pre 2013 trucks don’t have Thermal Bypass valves on them.
Took the truck for a good test drive up a couple good climbs and never got over 185 degrees now.
I still am annoyed at Chrysler for putting a heat exchanger back onto the side of the block. Going to do a bypass on that next time he comes up for service.
And the fact that they are using The top third of the AC condenser for a trans cooler on this truck just amazes me. There is plenty of room in front of the radiator for a cooler, all we need to do is move the horns and modify the lines a bit.
This over heating problem was absolutely from the TBV that I didn’t even know it had. Oh and the trans shifts AWESOME now.
