If they pulled the fill plug while it wasn't running,and drained enough fluid to actually check the fluid,you might want to do a fluid level check sooner then later.I've had the tranny checked by the dealer twice. The response both times is that the tranny is good and the fluid looks good. Specific questions about the TMU and TBV were given a short answer of "They were OK".
Edit: I am going to be installing caulk04's modified TBV in the next few days and check the AGS. I'll post the results.
Check your A/C condensor over for a bug/dirt build-up. The transmission cooler is in the top half of the A/C condensor,and if it's bunged up with bugs/dirt etc.,your transmission might run warm. I'd pull the grill spray some bug/tar remover specific for condensors/radiators on the condensor and wash the condensor out at your local carwash first,and then go from there. You can also remove the middle slats from the active grill shutters,just leave one top and one bottom fin in place,and the truck won't throw a code ,that's if you still have the active grill shutters in placeIt happened again........Went to Atlanta today, doing some hot highway driving, temps here are around 85 degrees. Was fine on the way down from Northern GA tranny temps were at 145 degrees at 80mph. But on the way back it jumped to 235 while my coolant was at 201 and my oil was a little higher around 203 - 209 at 70 mph. This went on for 30 miles till I hit some crawling road construction. So for a couple of miles my average speed was 5 - 15 mph. Once I got thru that temps dropped to 165 degrees and stayed like that all the way home doing between 70 and 80 mph. I already have CAULK04's thermo by pass installed and it works for the most part. Does anyone think that I may need to get my transmission flushed for debris possibly and have new fluid put in there? Any suggestions, please.
