Whats up guys, happy almost Friday!
I come to you for help troubleshooting, or confirming my suspicion about my tans in my truck, 1997 F-350 7.3 diesel with the E4OD
To start, whenever the truck is cold, the first few sets of shifts are SMOOTH as butter, feels new. Once it warms up however, it starts to act up. 1-2 becomes a bit hard shifting, 2-3 is smooth all the time, 3-4 feels like it falls into gear it's hard to explain(if it does it hard enough you could bob your head forward a bit), and 4-OD I think is slipping(it's not revving high, but it sort of "rev matches" where it bumps down a couple hundred RPM then goes lower into its normal range, which I classify as slipping until told otherwise)
Here is an album showing the color of the trans fluid, it's not good just a warning. http://imgur.com/a/RHSBQ
I'm going to go out on a limb here an say I probably shouldn't change it and the filter, probably just leave it alone
For those who know these trucks, maybe you can help. Apparently that 1-2 hard shift indicated that the trans is in "limp mode" using line pressure instead of solenoids to shift. I was unable to pull trans codes, but I will try again, but I have no lights and it wasn't under DTCs in my friends scanner. I know these can be very finicky transmissions, I just replaced a rear speed sensor because I was getting an ABS light here and there and I noticed my speedometer jumping a little bit time to time.
I also read the the throttle position sensor on these trucks can greatly affect transmission behavior, looking for someone to chime in on this.
My assumption is that the lovely E4OD is on her way out and that I'm on borrowed time, but if anyone has any helpful advice, I am all ears.
