To be honest.........same stupid symptoms last trans had. Re cap over the last week.............
First 3 days trans shifted solid, very firm, and consistent. Then it started shuttle shifting the 2-3. As in one time it'll shift at 20, the next it'll hold 2nd til 30. = gov pressure problems right..........through it on the scanner and it proved this. Actual gov pressure was all over the place below about 30mph. And sometimes doing a nasty shuttle back and forth.....ya know the shuttle shift non sense.
I changed the gov pressure solenoid and gov pressure sensor. Jeff agreed, it sounded like the "transducer" (as he calls it).
Made no change at all. It is now shifting the 2-3 shift VERY softly and more sluggish (this has been going on since about day 3.......progressively getting worse). The 1-2 shift is still strong, etc........
The 2-3 has a mild "bind" to it as well.
Now, minus the getting softer thing........the shuttle is not consistent. Not even close. May drive for miles at 25mph...........and then out of nowhere it freaks out. May not do it for the rest of the day. This makes me think it is something in the truck (harness, wiring, etc.........).
I have not yet got it on the scanner to look at things after I replaced the solenoid and sensor. Doing this tomorrow will hopefully tell a lot.
