Front differential dry, now check engine on and no power at 1st start. Code 52?

What is your question?

Got my oil changed with sluggish 1st gear issues the past year. Codes 12, 33, and 55 came up. Found out at oil change front differential was dry, rear was low with leak. Codes were 12,33,55,& now 52 that disappeared after oil added to front differential. Drove it after fill up. Worked gears with smoothing out in shifting, but slight grinding in 3rd and reverse on and off. Now check engine on whith major sluggish. Parked it, broke, and only have a bridge card. HELP! Appt. with shop in 2 days I have to borrow just to do, any suggestions besides a transmission replacement or rebuild? Most all my sensors plugs and wires replaced trying to figure out the 3 codes.
