I have a 1989 K1500 350tbi with a 700R4 that has been having an intermittent vibration or shuddering motion only in reverse.
No issues with moving forward but when it happens in reverse the truck will stop rolling backwards like it's in a bind and then I press the gas is when the jumping/vibration issue happens. When the truck is not experiencing the issue in reverse the it's smooth like normal. Also this issue has been happening going on 7 months now.
I have been under the truck and checked the driveshaft/U-joints and everything seems okay. However I'm far from an expert and if anyone has had a similar issue or any advice would be greatly appreciated.
I need to replace the kickdown or TV cable because it no longer locks into the bracket on the TBI but I don't know if that matters because the truck still shifts without issues.
