I'm running a TH 350 in my bucket with a Mr Gasket shifter from Auto Zone. It has no provision for a reverse lockout. I accidentally nudged the shift lever into R as I was leaving my driveway and it 'bout broke my neck! In heavier cars shifting to Reverse while driving will likely just trash the transmission, but in our little T-buckets it results in a neck snapping, tire screeching full stop, and at any speed a likely spin out or roll-over crash.
