Holley-Equipped Posted April 7, 2020 Share Posted April 7, 2020 I was wondering if anyone would know a reason why my GTO's engine dies when I shift into reverse. It has a 428 and an automatic transmission. Link to comment Share on other sites More sharing options...

Also have someone help you to observe the engine at Idle or fast Idle shifting from drive to neutral to reverse to make sure your engine mounts are good and not pulling the harness.

mike brady Posted April 9, 2020 Share Posted April 9, 2020 Also check to see that your shift linkage is not interfering with any wiring. Link to comment Share on other sites More sharing options...

Seen that many times. The engine twists right up in its mount and shorts out or disconnects enough to shut it down. Open your hood, shift into drive, hold the brake with your left foot, and give it gas. You should be able to see your air cleaner and if if moves much. Then check reverse the same way. If it dies immediately, before giving it any gas, then you need to look at your linkage as suggested. Link to comment Share on other sites More sharing options...
61polara Posted April 12, 2020 Share Posted April 12, 2020 (edited) Let's go back to basics here. We really need more information on exactly when this happens. I'm going to assume that you drove the car into the garage and just cranked it a day or so later. Put it into reverse and it stalls. If this is the case, your idle speed and choke settings are at to low of a speed. If it happens every time you shift into reverse, then go back over the comments above.

Pfeil Posted April 12, 2020 Share Posted April 12, 2020 I'm going to assume HOLLEY EQUIPPED is long gone. 1 Link to comment Share on other sites More sharing options...
