Hi 

Who makes the best quality transmission mounts for my 64 Sedan DeVille (with a Turbo hydramatic)? Rock auto does not list them.

Thanks!

I know Steele Rubber will revulcanize for $135. Kinda steep so you might check around. Here is the link:

Caddy Daddy has a repro for $79, and rebuilt for $145, plus $100 core. I purchased the repro and it looked pretty good, everything lines up. It is presently on the transmission, but the driveline is still out of the car, so I have not used it under power yet.

Here's a link to the repro -->  https://www.caddydaddy.com/shop-parts.html?cat=580&prod_year=498

Thanks. I don't think my current one is bad, but it is still original and there's no reason not to freshen it up. Question: Do you have to take the driveshaft out to replace?

Thanks

Norm

No, You shouldn't have to. Loosen all four bolts first, then remove them. Get a small piece of plywood or something that fits against the transmission oil pan, then jack it up a little with the wood and a floor jack. You should be able to slide the old mount right out. I don't think you would even need to disturb the crossmember itself.

In my case, the trans had a massive leak in that location, and the oil destroyed the rubber part of the mount. If that seal is bad, the driveshaft DOES have to come out for that.

Thanks! 

One more dumb question. Does it "relieve" the weight on the tranny to loosen the driveshaft center support bolts thereby allowing a bit of upward movement of the drive shaft when the tranny is lifted? Or am I overestimating the amount of travel required of the transmission in order to permit the removal of the mount?

Thanks

That would probably be a good idea. It would provide some slack for movement.

Thanks!

1963 series 62 convertible transmission issue

Posted by Matthew VanDeWater on June 22, 2021 at 3:03pm 1 Comment

Hello I've been restoring a 63 for way to many years. Down to almost done, but have issue with trans linkage, when column in park shift rod 2 inches short. everything original. been trying to find picture of manual rod hooked up from under car to see position of linkage. was wondering if anybody has access for pictures. I wanted to see if my manual linkage is bent  wrong out of the trans if somebody dropped the trans or something. Doesn't make sense why it doesn't work. Thanks for any input…

Torque converter grab when idling in Drive

Posted by Cliff Johnston on June 14, 2021 at 8:47pm 2 Comments

Hi Everyone, been quite a while since i have been on here.

I have had an issue with the idle on my 64 Coupe Deville ever since i have had it.

With the Idle set high enough that it is smooth, but still a nice idle, the RPM seems only slightly too high for the stall of the Torque Converter. And therefore it tends to sit there and grab and lunge a bit. So until now, i have been putting the car in Neutral at the lights to stop this happening.

I've had the car dyno tuned and…

Can you help? Driveshaft Question....

Posted by Chris on May 30, 2021 at 8:55am 1 Comment

Hello!

Newbie to the group here - we have already found tons of invaluable information on the board, so thanks! We are restoring a 1963 Series 62 Convertible. We are wondering if anyone knows of a source to buy the propellor yoke flange (that bolts to the pinion flange) for the driveshaft? One of our ears partially broke off. Not sure if we can buy just the yoke flange as an aftermarket part, or if it has to be rebuilt by a welder/fab guy? Maybe a salvage yard for a source? Again, any…
