trans temp issues

Hey guys I just had my trans rebuilt by a shop, i blew out all of the lines, changed the trans cooler, added OEM fluid, and changed my trans bypass filter.

The trans get hot on my ride home on cold days. Last night i was at 208 by time i got home which is about an hours ride from my job. Outside temp was about 45.

I have the 26 row cooler, diesel site bypass filter and stock pan. Before my trans failed on a day like that i would run 160 no problem and it would sit there with out budging.

if I cant figure it out my next step will be to drop it off at the shop who rebuilt and have them look at it. They didnt have the truck to install the trans back into since i pulled it and put it back, so they didnt have anything to test.

Thanks,
AJ

Run a flow test if you have not already. 1.0 qt/15 sec.

First, Have you checked your fluid level? 208 is warm for empty but nothing to be concerned about, I agree something is going on.

fluid is at the correct levels hot and cold. How about the bypass valve on the side of the trans? ive had that fail on me before but im guessing none of the trans lines wouold be hot if it was just bypassing within the trans

I'd call the shop and see what they say. Maybe Mark K will drop in and have some advice for you.

My SWAGs are the either the bypass is leaking or the trans cooler in the radiator is partially plugged.
