Auto 3 spd. or 2 spd Column ?

[mjgord51]

Can any body tell me if what is pictured here is a 3 spd Auto Column or is it a 2 spd Auto Column shift. If it is a 3 spd where I have a arrow pointing at the area with a dit dot dash lines and a X in it can that area be cut out for making it work as a 4 spd column shift? I am trying to use the Original column for a 700R4 trans. Am I asking too much or will I just get my self in trouble trying this, LOL what could go wrong. Thanks, mjgord51

I used a Powerglide column on a 700 trans and didn't have to do anything. The shift indicator position is wrong, but all the gear selections are there if manually shifted through. I'm not sure what you are trying to accomplish by cutting that section out of the column.

If the column I have shown is a auto 3 spd (350/ 400) trans than I was thinking that area I wanted to cut out might be good for the extra gear (700R4) 4 spd, would that be wrong in thinking that might work,*** just thinking it needs more room for the extra gear ***. Or would there need to have something else to modify like the inside tubular part ( I dont know the name for it) thats inside of the outer "Mast jacket", the part ( tube shaft) that when you shift it comes in contact with the neutral safety/ back up switch, Iam just guessing that some thing else might need to be altered. . What could go wrong- right. mjgord51

When you say "The shift indicator position is wrong Iam a little confuesed there, my old 64 SS Impala had a power glide that the shifting pattern was " P,R,N,D,L." The only difference is the 700R4 has " P,R,N,D,3,2.1." can you explain a little better, Thanks, mjgord51

I understand what you are saying now. It is not necessary to cut the outer part of the column to get sufficient shift arm movement to select all gears on a 700 trans while using a Powerglide column. But, I still have PRNDL indicator window on top of the column inside the truck, and the pointer does not line up with the gear markings on the window except in Park. When I shift the truck into gear, I just count the clicks from moving the lever. I have not been able to find an indicator window marked for the overdrive trans. Apparently they are not available for non-tilit columns.

I am also working on the indicator problem, maybe one of us will think of something that works. when I fix my problem/ project on the shifting I'll let you know, If you find some thing that works first drop me a PM and if I find it first I'll drop you a PM, deal? Marvin aka mjgord51

Good deal, I'm sure you will be able to make it work. By the way, I also used the lower brackets from a 77 model bolted to the frame instead of the older model. I figured it would work better with the 700 trans.

I have a 700R4 trans in my Blazer it works fine. The trans starts out in !st gear no matter where it is on the indicator so it will work even though it is not showing !st.e

In my experience, the column itself has no detents below the "Drive" position, so it will work with TH350 or 700R4. (I have no PG experience.) However, you will need to adjust the linkage rod so the column detents for P,R,N,D correspond to the trans selector shaft detents. Detents for lower gears are only on trans, not column.

You can get a 700R4 gear indicator for a 67-72 column from Ididit.

On my 82 C10, I had to buy this one when I converted from manual to TH350. It mounts to the dash, and a cable clips on to the shifter "bowl". It's for 79-83, as I recall.
