HELP!!!! We used to use shifter cable with powerglide. New headers have burned/melted the boot and combination of engine setback and shifter position dictates I go to metal linkage. The old stuff we used on turbos won't work. We fabricated stuff last night but it's not working out due to angles and tunnel clearance. Anybody have any quick fixes or suggestions for Powerglide transmission linkage problems. Three days to first race. Also, I run in Drive and need to shift!

When I had a glide, I used a 1/2" square tube with 1/4" bolts at each end. 2 things I should also mention - I had the aluminum powerglide shifter lever from Speedway (it had a spring to let it move some) and my motor was mounted solid so there wasn't much movement between the shifter and the trans anyway.

If your motor and trans move around, this set up might not work.

We run powerglides on 3 different cars and have always just used all-thread with a nut or washer welded on it to attach to tranny & cut a hole in the floor board for the rod to stick trhough. Shift into gear and go.

Your not shifting during the race are you???

Just make sure when you fab the bracket for the tranny side that you allow at least a couple inches in length for shift feel..i made mine too short for clearance and it would go from park to low moving the shifter about two inches.

I welded a 1" plate about 2 1/2" long to the shifter linkage coming out of the trans. straight up and used all thread. Cut a hole in the floor board and attached to my shifter. Works great! Before I welded the tab on I used stock trans lever, but I had a reverse shift pattern. (?) Hope that helps. Race

Thanks for the feedback. We fabricated the mounts last night and it's now working. Isn't all thread GREAT??? Yes we do shift during the race and are now working on making a detent in the shifter to stop it from going into Neutral or Reverse, if I get too physical. Thanks again for the responses and advise.

Just always be sure that the shifter is not holding the tranny between "clicks" on the tranny. The lever on the transmission should be holding the car in gear, not the shifter in the car.

I'd also work on finding the right gear for your rearend so that you don't have to shift the tranny. For example I run in low 1.76 with a 3.55 gear comes out to 6.24 works great on a 3/8 semi banked track. I could not imagine having to shift, along with all the other things I'm trying to pay attention to in the car.

Last years car ran in low 1.76 with a 3.08 giving a final drive of 5.42. I was constantly killed on restarts running with only one gear. Most everyone else shifted to keep the rpms up. I installed a 5.38 ring and pinion, I bought from Pickel in this rear end to try to hold my place on the starts......so I made a conscious decision to shift. Thanks for the reply.
