'85 TC Stall in reverse

1985 TC stalls when put into reverse. When put in reverse from any gear, the RPM's shoot up a bit then it dies. This started happening last fall before I put the T-Bird away for the winter. The only mod that may coincide is a Gillis valve that was installed last summer. Any ideas? Thanks!

....should add: it's an automatic trans....

Check for vacuum leaks and clean the IAC as a starting point. Also run a complete code test (KOEO, CM, and KOER) and report back with any codes present.

Did they use an automatic release on the parking brake? My TC does not have that, but it's a 5 speed, so they couldn't. Those (on a lincoln) are vacuum powered and of course it comes on when you come out of park. Fundamentally I would expect to find a vacuum leak there and some parts of the system semi-working.
