400s work similarly for 2nd. They do have a band for lo/rev , rather than clutches though.

Good morning to all,
When I first read the post I thought that a lip seal might be the cause, but since it had reverse before, Marks comment on the frictions is probably pretty close to the source of the problem. The TH250 has a" Band Apply" for second gear as does the THM200. I would drop the pan and inspect for friction material and anything metallic. If there is a lot of debris in the pan, I'm not an advocate of running all that junk through the trans and possibly jamming up a valve in the valve body or ruining the rest of the frictions in the trans. This is why a good many racers have Spare transmissions with them. Take a look and go from there. Good luck on your Quest.
Respectfully,

P.S. Check with other racers and see if someone local can help look at the trans. G.M. built those transmissions by the thousands - meaning there's stuff around that might be able to get you through the weekend.
