stuck in reverse, Transmission is stuck in reverse Options

[PCH]

Hi Everyone!

I took my ‘71 1.7 to the car wash yesterday. When I picked it up, they told me it was stuck in reverse.
Sure enough, the gearbox is stuck in reverse. It seems like you can shift back and forth between 4 and 5, but in those positions the gearbox is just locked up; feeling like “park” in an automatic transmission. Shifting back and forth in neutral only left the gearbox in reverse.
On my initial search of the internet, I came across mentions of a car being shift ed between first and reverse while still moving and this could cause this. Also there was a mention of doing something with the reverse light pin to get it out of reverse.
Is there an emergency fix for this problem and what is the long term repair?
Thanks everyone,
Peter

Happens when side pressure is put on the shifter when moving to neutral. Drain the box and remove the cover where a side shift console would bolt up. Move the 1st/reverse shift rod into the neutral position and reassemble.

Also there was a mention of doing something with the reverse light pin to get it out of reverse.

This works on a 911 where the reverse switch contacts the end of the shift rod rather than the side. You'd remove the switch and push the rod to the neutral position.
