I solved the leaking speedometer gear leak on the transmissions. If you take the housing out of the tranny, and remove the pinion gear and shaft, there is a O ring in the housing. Pop it out with a dental pick, and size it up at the parts store. I installed the new O ring in less than a minute.   One less leak to worry about.

Ok thanks for info !

I dont see a need to drain the tranny. Just run the engine for a few minutes, just in case the tranny has internal leakage (good call David).  Have a catch pan ready, just in case.

Hello, I sometimes lose my oil Turbo Hydramatic TH-400 transmission. Also known as the small O-ring that is in question. I would like to place a new O-ring, is work hard, should we drain the transmission oil? Thank you for your

This is a fix you can do on the 63 Hydra-Matic without loosing fluid. Unless all the fluid is in the bottom of the transmission from internal leakage. The shift linkage O-rings are another source for external leakage. Unfortunately, you have to drop the pan to get at those.

Good Post Russ, The spedometer drive was a pesky leak I eliminated on my 63's transmission, also.

Good information. I put a link to this thread on the Help Topics Page.

Tony, the fix is for the Hydra-Matic tranny.  Should be the same for the Turbo.   I pulled the piece out of my parts transmission,  so I dont know if the tranny will leak when pulled.

Russ

which trans does your fix apply to  ?

i think your 63 has a hydromatic

did you have any issue with trans fluid leaking out during the repair ?`

Hey guys hope you’re having a great day. I have a question about the choke heater tube. Mine is loose at the intake and seems to be causing a vacuum leak. Any thoughts on how to seal this up?

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…
