Also make sure they did not use some Universal Fluid.
ATF+4 is all that will work on a 545RFE.

x2 - about half the folks getting Suncoasts installed got the wrong fluid - even if you tell them up front - they don't believe it's an issue until you start having problems.

I took the libby in to have the trans flushed and filters replaced by a reputable local shop. I got it back and I am now getting shudder from the TC I assume in the morning on cold starts. I get a little shifting into reverse, but much more once braking down from 10mph to a stop. It is like the engine is surging and the brakes are having a tough time holding her back.

I did get some TC shudder before the flush and filter under heavy load 50-55mph, but never while on cold start at low speed and durring braking. In reading some posts I am assuming that there is in issue with the drain back valve due to the cold start issues. I also am wondering if this shop put proper fluid back in the trans.

If I have to have the trans opened up for valve work, should I just have the TC replaced?

Thanks for any input,

This supposed fix was found to be false, because when i left for work this morning the shudder was back. I asked what kind of fluid he used and he said Dexron IV. He said that this is the latest and greatest fluid and he uses it in everything. Should I demand that he drain and refill with ATF+4?

Definetly have him get every drop of the WRONG flud out of your transmission There is NO ONE SIZE FITS ALL and expecially on your CRD.

This is a very old story and has been done by independent trans shops many times because they only buy one type of fluid in 55 gallon drums

Good luck draining/flushing the torque converter with out pulling the transmission.
Over the years I have only seen a couple cars with drain plugs on the torque converter and a way to get at it when in the car.

If they have shop insurance that is worth a hoot, their insurance will cover it.

[It's called a trans flush,flushing 28qts(twice what your 545RFE holds) will do the trick.

Well I kept getting the run around and found someone else at the shop complaining when I went back today. I insisted on my money back which he ended up providing. I am taking it in to another shop Monday morning that is going to allow me to watch them tear down the pan and flush and fill. Hopefully there is no damage done. Thanks for all of your help.
