Default 67 Shift Linkage Adjust Problem

67 Driver small block 4 speed stock shifter. Only goes into reverse after many minutes of fidgiting with shifter. I'm assuming she needs linkage adjustment.
I'm under the car and no way I can get to the shifter to insert gauge tool. Removed exhaust and still can't get to shifter. The trans mount/exhaust hanger blocks
coming in from the front, and the hand brake pulley/bracket blocks getting to the shifter on the rear side. What am I missing here? Please I need advice
on how to get access to the shifter so I can insert special tool into the shifter.

Thanks much. Ox

I took the console out and went in through the top. I did not use the straight one, I made a bent up rig out of a strip of brass shim stick that I bent and cut so I could finagle it in from the top. I feel your pain.

I recently bought installed a new repro shifter and had a similar issue with reverse…

I had an idea, and just adjusted the reverse rod only, from under the car…. Because I didn’t use the tool, it was Trial and error, but wasn’t too bad…. 15 minutes and I had reverse working smoothly…

1-2, 3-4 were fine…

I have a 67 and had a very similar experience when I bought the car. Shifting was so bad that the car for the most part was un-drivable. I was able to access the shifter from the bottom and was able to insert the shifter adjustment tool from underneath as well. It wasn't easy to insert the adjustment tool by any means, but I was able to do it. I seem to recall that I disconnected the shift linkage rods from the transmission and let them hang straight down in order to gain access to the alignment slot in the shifter. See posts 3 and 6 in the following thread: https://www.corvetteforum.com/forums...djustment.html

Default Surprise!

I've been futzing with this now for way too long. Good thing I have a Quickjack because I was must have been under that car a gazillion times. I even broke a caster on my many years old trusty creeper. I tried all sorts of schemes to try to get some kind of gauge into the shifter mech and was only partially successful due to extremely limited clearance in the tunnel. Exasperated, I was about to remove the exhaust hanger which would've given me a little more room to maneuver but that would have required that
I also take off the trans mount and I didn't feel like doing that unless I had to. SInce 1-4 shifting was OK and the only problem was that it wouldn't go into reverse, I decided to just mess with different settings on the reverse rod. But no mater how the reverse rod was adjusted, there was no change in the problem. Couldn't pull up the reverse T-handle and therefore wouldn't go into reverse............Duh!!!!!!!!!!!!! Couldn't pull up the reverse T-handle??!! Wait a minute. Brainstorm time. Just on a whim, I started unscrewing the (after market) shift ****. Guess what? Yea, dumb me. Unscrewed the ball about a turn and a half, the T-handle goes up a little further, flips into reverse no problem. Well I'll be damned. Here I spend endless greasy hours under the car and all it was the shift ****.

So, now I've got to spend hours looking for the old original ****. Hope I can find it. Anyone ever have that problem with an aftermarket ****? It's threaded just a thread or two too deeply. Anyone know where I can find a gen-u-wine OEM ****? In the meantime, I'll try sticking a washer or two up inside the **** so i can't thread so far down on the shift shaft and prevent the T-handle from raising all the way. I think that'll solve the problem.
