A quick question, if I am at cruising speed and speed up slightly on a marginal incline and the car studders like a rumble strip when unlocking the converter, is that torque converter shudder? It doesn't do it if I speed up aggressively and down shift nor does it do it when I accelerate and brake to test the lock up. Only on gradual acceleration and mostly when using cruise control. I did a fluid and filter change with DEXRON III about 3 months ago and this has started in the last couple of weeks. It does not do it going into fourth gear only coming out.
The car did a more violent version 5 years ago when I bought it and had cleared up with fluid changes and some shudder fix. I did not replace the shudder fix when I did this fluid change instead I did the Lube Gard ATF Protectant. Should I still use the Shudder Fix?

had my 94 rmw doing that, but I had a full flush done on it, not just fluid and filter, and the shudder went away, my car only has about 153,000 miles on it though.

This one has 132,000 but the previous owner wasn't as attentive nor did he drive it much. I daily it.

You can get a shudder stop at NAPA. It worked temporarily in my OCC until the 3/4 gave up.

Speaking of neglected trannies, i came across a tip suggesting that one could siphon a quart every 3000-5000miles- like same time u do an oil change and add some fresh trans fluid. I recall this was in a video in changing the transmission filter which i would think most all the fluid wouldve come out then anyway.

The trans holds 12 quarts of fluid.

well you might get lucky doing a full flush, as it's recommended at 100,000 miles so your only 32,000 miles over, I was 50,000 over when I had the tranny flush done, and it was because of a shudder like what your talking about.

Oh and I didn't have any additives put in after the flush or since then and no problems even with a load in the car on the highway at speed.

I think this was a suggestion as a way to deal
With a neglected trans without it being a shock to the system. I wondered about this as my last wagon had been neglected and ended up having a full flush service done around 145k and i think within 10k miles is when the 3/4 went out after that was done. Also had an 2003 xj8 which they touted as ‘service free’ transmish which of course wasnt the case - it just meant there was no drain hole for the fluid🙄 but they were known to fail without being serviced after 75-150k and mine was at 124k so being as a trans cost more than the value of the car to fix i decided to sell it before anything happened.
