Autostop Eliminator


Recommended Posts

I bought and installed the AE30 Harness for my 2021 GMC 1500 5.3 SLT.  It does swap the start/stop to disabled as intended.  Does anyone else get a light shudder when stopping?  It seems to me the shudder started after installing it.

 

Thanks

I have the same harness and glad to have it. This has happened to me exactly one time in 4K miles. I read up on it and there is a link between having the autostop off and the stutter. I ran it a few times with autostart on and then put it back to off. Hasn’t happened again. Yet.

I have had the rough shift problem since about 500 miles. It lasts for about 3 days and goes away for a few weeks and then comes back for another 2 or 3 days. I installed the Auto-stop eliminator at about 2500 miles, it has made no difference in the transmission problem. I now have about 4000 miles.  Unfortunately your rough shift into low will probably come back, like mine is continuing to do.
