FL-Roam Report post Posted April 8, 2021 Starting to tow a 2017 Acadia (same as 2018 and with keyless ignition) and my manual has the opening shifter boot and releasing the white lever to shift to neutral procedure. That works fine. But I realized there might be an easier way. How about just starting car in park (as normal), shift to neutral, and shut it off? This works and leaves car in neutral. I haven't towed it after this procedure, just wondered if any one knew why this would be a bad idea ? Share this post Link to post Share on other sites
rossboyer Report post Posted April 8, 2021 While it is best to contact GM for the reason, I think that the white lever you referenced disengages the transmission from the drive train to prevent the wheel rotation from back driving the transmission. Share this post Link to post Share on other sites
manholt Report post Posted April 8, 2021 FL-Roam. Welcome to the Forum! It has been my experience, since 1985 and a lot of different brands, to follow the instructions in the owners manual. Share this post Link to post Share on other sites
five Report post Posted April 8, 2021 Ditto to what Carl said. If there is doubt, check the owner's manual then call the manufacturer....compare the results. Share this post Link to post Share on other sites

Punch small hole in boot and use small screwdriver to punch button to put in neutral. Share this post Link to post Share on other sites
rossboyer Report post Posted June 30, 2021 If that happens, install a charge line. I had to for our Chevrolet Equinox. Ran #10 wire from battery to RV electrical outlet for towed. From towed’s connector again #12 wire to towed’s battery. I used a 20amp circuit breakers on both ends You need to protect RV wiring and towed’s wiring Share this post Link to post Share on other sites
rayin Report post Posted June 30, 2021 Welcome to the FMCA discussion forums! If the transmission is not disconnected from the driveshaft the internals of the transmission will still turn but not be lubricated. Only with the engine running does the automatic transmission oil pump operate to supply oil to moving parts. Share this post Link to post Share on other sites
