Automatic transmission slipping after fluid change

Asked by Stormcustoms Jun 01, 2018 at 01:15 PM about the 2013 RAM 2500 Tradesman Crew Cab LB 4WD

Question type: Maintenance & Repair

I have a 2013 RAM 2500 Cummins
powered. I changed the fluid in the
transmission but didn't realize that there
are two filters and didn't change the spin
on filter. I filled it up and upon test drive
it was shifting funny and just acting
strange. I kept checking the fluid level
and added as needed. This morning I
got in it and it started slipping after
about 10 miles. The old fluid didn't smell
or look burnt. Is something stuck in the
valve body maybe?

Did you use the correct fluid? By correct I mean the exactly correct fluid specified, not a generic one size fits all fluid.

No guys it's the+4 fluid that it calls for. It's fine until it tries to shift out of 3rd gear, it's like something is not closing in there. But no slipping from take off until that shift
