    Codes po933 and po732 help

    Trying to figure out how screwed I am and what to do.

    Got these codes po933 and po732 while towing a vehicle out of the sand.

    My mistake had it in 4wd high and not low.

    Truck is a 2018 2500 with the 68RFE 48,000 miles deleted and tuned with 35 inch tires with stock gearing.

    Was on the 90 or 120 hp tune cant remember.

    Truck ran and shifted fine the rest of the day. Cleared codes and towed 10k camper home 200 miles fine yesterday.

    Did notice trans is running around 180° instead of around 172 like normal.

    Around 300 miles driven so far and everything seems normal except temp is a little warmer.

    Codes have not returned.

    Anyone seen anything similar?

    Is it time to get ready for new trans?

    Think of it as opportunities for upgrades rather than how screwed.

    Most likely had to slip the LR clutch pack with those 2 codes.

    Might go a long time with no issues or might get worse tomorrow.

    I toasted 5th gear.

    I've said this a lot on here, but 35s with 3.42s are a 68RFE's worst nightmare.

    I haven't seen it do much damage to the low gears, but the sand situation, 4 high, and pretty hot tune, makes sense to me that some clutch pack damage occurred.

    Unfortunately thats what I was thinking also.

    Probably change the fluid and filters this weekend and hope for the best while I save for upgraded trans and maybe some 4.10 gears.
