HELP! Transmission fluid

[dub02gpgt]

This one appears to be newer and mentions a DEX fluid?

Also says to drop the pan and I'd shavins are present replace the torque converter...

Thoughts?

Yes, I see that they did my 2017 8 months ago and put Mobile1 Blue label and the TSB I linked is what was on repair order, Maybe GM had same blend made under their product. Since I had mine done, I have not had problem that I had with shutter since flush.

 

[dub02gpgt]

What mileage were you at then? & how many miles have you put on since?

How long did it take before the shutters dissapated?

Did you request they drop the pan and replace the filter or just follow the TSB?

 

[Blackcar]

It started shutter at 19000 miles and has 23000 on it now they said not to expect it to go away until I drove 200 miles. Does yours have dip stick for transmission?

 

[dub02gpgt]

It does not.

 

[Blackcar]

The TSB you have says to put fluid thru dip stick tube that's weird. Oh, and they didn't look at filter it was warranty, so they aren't going to do more than what's stated.

Well, I went with the flush only. I've put about 130 miles on mostly highway (75-ish), I haven't noticed as much, but in my case it was most noticable between 40 & 65.

I'll post another update once I have a little more experience in my problem range...
