Saturn automatic transmission problem

Asked by May 04, 2016 at 07:21 PM about the 2002 Saturn S-Series 3 Dr SC1 Coupe

Question type: Maintenance & Repair

I have a 2002/sc1 Saturn 3door 1.9l 4cylinder
engine. It jerks when shifting from 1st up, it also
tacs up to around 3500-4k before attempting to
shift. Also it shakes my car when shifting from
neutral to first. No loud noises no screeching just
hard shifting, high rpms before attempting to shift,
and jerks when going into drive. I’ve replaced the
transmission filter and filled it with the correct
transmission fluid and ammount of transmission
fluid per my owners manual
I just can’t figure this cars problem out. It has 156k
on it but up untill this randomly started happening
it drove fine with no problems. The only code it’s
throwing is the secondary air injection pump, but
that seems to be working on a cold start. Any
ideas?

Try adding some Lucas Transmission Stop Slip it can help with hard shifting. Do not over fill

Did you resolve this issue. I'm now having an identical issue.

Don't use Lucas. It the line pressure sleeve in the transmissions valve body. Buy a sonnax updated valve body on ebay for 200$ . had same issue with my saturn sc1.
