63 Hydra-Matic won't shift out of first

[Norm Waters]

Hello everyone. I had a perfectly good shifting Hydra-Matic transmission until I elected to fix the leak at the dip stick tube. I just did a quick seal with gasket maker since my current tube is missing the mount and I was headed to the Lead Sled show in Salina, KS in a few days. I drained about 2 quarts of fluid so I could do a good cleaning around the inlet and under the dirt flange of the tube. Installed gasket maker and reinserted the tube then let it sit for 24 hours. Topped off the fluid level the next night and took it for a test drive and now I only have park, 1st gear and neutral only. I have run the diagnosis in the manual. Reverse table is normal, low table is normal, third table has no 2nd, third or fourth, same results for fourth table per the manual and neutral table is normal. I would think I could assume no broken parts and this is a result of possibly stirring up debris from refilling the transmission. If so if I get into the valve body will I need new seals or is it a take apart clean and reassemble process? Could the governor be suspect and if so should I start there?

On the bright side I did stop the leak.

Thanks

Norm

Yes got the everything up to temp and checked level it was a about half a pint low. I left it running and added to the full mark. Still nothing above 1st gear.

Only think I can figure is that debris fell into the trans and settled into the governor.

Russ I believe you are right. I went back out and ran the diagnostic tables and came up with a condition 2-9602 which is an 11 on diagnosis index chart. See attached chart which would lead me to believe it is the governor. I'm waiting on the delivery of the extension to rear pump gasket to clean the governor. It does mention the G1 governor valve stuck but I’m not positive we’re that is located. My guess it is located in the valve body?

Thanks

I thought that as well except that valve is called G2 on the exploded view in the manual. I can't find any mention in any exploded views of a G1 valve. There is a G1 passage in Fig 6-6 transmission case oil passages.

Thanks

Thanks for the reply, so there isn’t a G1 valve as stated in item (a) “G1 valve stuck closed”?

Thanks for your continued help, I just want to tear it apart once.

Mark, Russ and Tony

Thank you for your reply’s and the willingness to help a new Series 62 owner. I.m learning this sight is invaluable to the owners of theses cars. I know my way around a wrench but am a bit nervous about tearing into an automatic transmission. Given the fact the previous owner had copious amounts of RTV on the trans filler tube, conservatively speaking a full inch on the tube and into the transmission case, should I start at the valve body?

Thanks again!

Thank you again for all your help and knowledge. If the gasket gets here tomorrow I’ll give it a shot!

[Norm Waters]

It was the governor. Both valves were stuck, a good cleaning and refill and all is good. I was amazed at the torque someone had but on the rear extension bolts. I had to use a half inch impact wrench to break them loose! Same at the universal flange to pinion. 

Thank you again for all the help.
