Can anybody tell me if a powerglide speedo cable is the same as a muncie 4 spd one on a 64-67 Beaumont? I am having speedo issues. Thanks in advance, Paul.
I guess if it connects to the passenger side they are longer but the early muncie cars are on the drivers side so the cable reaches. I guess the gear in the trans might be hooped? Paul.
I changed the cable thinking it was defective but it still didn't work. So I put the car on my lift with the cable off the gauge and under the dash so I could what it it was doing as I ran the car in gear and it doesn't spin. It could be in the trans. Any advice? Paul.
looks like you may need to do the same thing I do.. pull tail shaft housing.. then the "sleeve", or put one on. My tranny was missing the "driven" gear off of the cartridge when I got it. (the one that fits into the "sleeve" on the tail shaft)
Well what a job. This is how it played out. I changed the cable and it didn't work, pulled the plastic gear and it was stripped so I changed that and it turns again. Hooked it to gauge and it didn't work. So I find out that the gauge that looked mint is seized, toasted the cable, and stripped the gear. I had to pull the steering wheel, dash pad, dash, undo all the wiring and change the cluster. What a pain. I have never seen a seized gauge, especially one with no corrosion and minty looking. It's fixed after about 8 hours and a few swear words. Drove the car with my GPS and the speedo is perfect. I was wondering if it was internal to the trans but thank goodness it wasn't. Just in case somebody needs the plastic gear set up for there car in the future I have 245 60 14 tires with a 308 rear end, M-20 trans, and the plastic gear had 18 teeth. Thanks for all your posts. I'm almost there on this rag. I'm a non charging alterater away from being complete. Paul.
I have a similar problem. Mine is M22, the cable was 2 inches too short when I bought the car, and just temporarily tied to the trans, seller had an adapter, but I told him not to worry about it, as I'd get a longer cable. Well I had the dash out last year, so I connected the new cable, and still no speedo action. I havent tried to solve it yet. If its a seized speedo, then it is staying that way, but if its just a plastic gear then I'd replace it. The green plastic gear is visible and appears good. I was following this thread closely, but dash removal it out of the question.
I just put a cordless drill on the trans end and checked if the gauge functioned. My gauge was locked tight. I managed to break it free but it still was not right. I also tried to pull the gauges from under the dash. What a mess. All in all if I just pulled the dash right away I could of saved myself a lot of time.
