Just bought yesterday.

I knew trans was shifting out of 3rd. I was thinking of getting a valve body with shifting solonoids installed. Do my own service when I can. Had codes read and cleared. Drove half mile they came back. Improper ratio 3 to 4, 5.6 not at all working. Fluid change showed nothing.

thank yall

Welcome to the forum James,

I've moved your question from New Member Area - Intro a MUST to S-Type forum. Members here with the same model will be able to help.

I hope you bought it real cheap as a replacement trans is more than likely in your near future.

Based on your description it is likely your E Clutch is toast. Replacing the valve body/solenoids will not rectify.

A few things to check on...

1) Is there any leakage/seepage in the TCM rubber sleeve. Is the TCM harness connector wet or damp?

2) Was the fluid topped off correctly. Dribble at 40 deg C then cap off?

3) When you drained the old fluid did you get 6 - 7L out?

4) Any seepage at the trans cooler lines? Pan??

If the trans was low on fluid (more than 2L) time to source a replacement unit as these rebuilt go between 5 - 7K at a trans shop.

You could also get the adaptions reset and flash the TCM but it sounds mechanical in nature.

These units are pretty good until they run low on fluid.

Good Luck

Make sure that your torque wrench can go that low or you may break the the New filter.
