Hard or rough shifting
Medium — fix within days
The transmission shifts hard, jerks, or clunks when it changes gears, instead of shifting smoothly like it used to.
Possible causes
- Low transmission fluid — Most likely · Codes: P0700P0841
Check first: Check the transmission fluid level and color. It should be red, not brown or black, and it should not smell burnt. - Bad shift solenoid — Possible · Codes: P0750P0753
Check first: Notice if the harsh shift happens in one gear only. A bad solenoid usually affects a single gear. - Worn transmission — Less likely · Codes: P0730P0780
Check first: Notice if the transmission slips between gears or the fluid smells burnt. Slipping plus burnt fluid points to internal wear.
