Occasional Engine Stall Shifting to Reverse

[taylorbr]

Thanks in advance for any light people can shed. The engine occasionally (once every 5 to 10 attempts) quits after I shift from park to reverse. And there is always a few second lag shifting from park to reverse and reverse to drive. I changed out the fluid about 4,000 miles ago and have a 1994 so I don't think it could be the faulty gasket. Original transmission, no lights or codes, and it feels pretty good going forward.
