Interesting it is the reverse giving the problem. When my old Jake with a Peerless transmission started acting like that the only gear I had problems with in the beginning was second which was the gear I run in 90% of the time.
Here's a thread about it over in another forum that might be of use:
801-038B Peerless Transmission
Also here's the service manual that covers the 801 series starting page 30 (PDF page 28)
