Ok, so after about 6 years of routinely mopping up oil spots on my garage floor, I decided to try and fix the leaks in my '65 C4 transmission. This included pulling the transmission and replacing the following:
O-ring seal in driver-side pump cover
Seal around band adjustment bolts
Seal for gear selector shaft

Now that I put the transmission back together and back into the car, it is making a LOUD SQUEAKING noise when I start the engine. The only thing that I can think of that was even remotely invasive was when I took out the valve body to remove the "gear selector shaft" to replace the seal. Also, I had to mess with the band adjusters to change that seal. Does anyone have any clue as to what could be causing this SQUEAKING noise? It sounds very similar to a fan belt that is very loose. Could it be something with the torque converter? Need some help here...

One more thing. When I shift the "gear selector shaft" from one position to the next, it only locks the driveshaft in the farthest to the rear position. Is this normal?

Sorry for the lack of proper terminology.

I did a quick search in the old posts but couldn't find anything about adjusting the bands. Could you give me an idea of how to do that? Thanks.

Did you bolt up the converter?

Did you use the right length bolts?

Did you bolt down the backing plate on the block?

I'm sure you did, just making some suggestions.

Is the drain plud in the converter lined up with the hole in the flex plate?
As per a recent post, it's possible to have 2 drain plugs that need to be aligned with holes in the flex plate.

If I remember correctly, the end of the band adjuster bolts slip into a fork which in turn applies pressure to the band. Is it possible that while replacing the sealing nuts, one of these adjusting forks fell out of place?

I also believe that the band adjusting bolts are to be tightened to 10 inch pounds with a torque wrench prior to snugging down the sealing nuts.

A good resource would be the Haynes Ford transmission rebuild manual which can be purchased at the local chain auto parts stores.

Did the converter seat fully into the pump when you slipped it on the shaft?

I have done that (forgot to line up the converter drains with the flexplate) and it made a horrendous squeeking noise! There are two, but as they are 180degrees out from each other if you line one up, you automatically line the other one up.

That is right...some torque converters have 2 drain plugs and they must be align with the starter ring (automatic)holes or you will get a scraping noise...I know, I did it !!!! :thumbdown: I will never do again. I first thought I got a warped plate.....A loud squeeling noise...mmmmm..I hear that all the time...the pig pen is not far from the shop!!!
Good Luck...Johnny66 in SC ...

Not always just 2...I bought a after market plate that had 3 holes. First time I line only one up but not 180 from each other. The 2nd time...I saw my error and corrected it.... :thumbup:

I think that's the problem! I crawled back under the car last night and rotated the engine by hand and discovered that the flex plate was contacting the starter gear in each rotation. After reading your posts, I think the flex plate is probably not sitting flush up against the torque converter and is making it wobble back and forth and contacting the starter gear. I probably need to line up the drain hole so it will sit flat against the converter. The squealing noise was most likely the starter gear vibrating from trying to spin so fast. Thanks guys. I appreciate the help.

Not really. There are 4 holes in the flex plate, all 90 degrees apart. ONE of them, though, is covered by the counter weight. So if you have 2 drain plugs, you have a 50/50 % chance of getting it right. If only one plug, 75/25, and if 3 plugs, you have a 25/75 shot of being correct if you haven't checked it all out first.
