Stalling in reverse

[1970 conv AS]

Hello all,
I have a 70 with 1600 SP I'm trying to get running. I pulled the engine and swapped with another i had.  Did not touch the transmission or converter.  I'm having carb isues (another problem i think i just need to get the choke adjusted). But when i do get the car running i can shift in all the forward gears no problem. When i shift into reverse it goes into the reverse position but as soon as i lift off the shifter the car stalls and sometimes backfires. Anyone have any ideas.  The shifter point has been replaced.

Thanks
mike

Hiya 1970,

Interesting problem!

First of all, do know that there is nothing different or unique in shifting into reverse as opposed to the three forward ranges.  Well, with the sole exception of having to depress the shift lever, of course.  But mechanically speaking, if you shift into the forward ranges you should be able to shift into reverse also, unless..................

There is something wrong inside the case.  This I doubt because you mention the backfire.  Besides, the AS is a very hardy beast and usually problems with this transmission can be solved without ever having to get inside the case.

So, I'm thinking of what might be different (about shifting in to reverse) outside the case and the only thing I can come up with is the back-up lights.  There are two in-line fuses on your 70 and they are located in the upper left hand corner of your fan shroud.  It may be possible that you have cross wired these guys or somehow cross wired them with the electric idle cut-off valve on the carburetor. 

Just guessing here, but I'd start looking real hard at those in-line fuses and the coil hookups.

Very well thought out Mike....

I wouldn't have thought of that...
