Recently drained the TQ/tranny, cleaned screen and new pan gasket.

Went through the start up per the FSM...Fill/shift into each gear ending in neutral.

Have driven it twice since for a few miles.

First time out noticed 1 or 2 hard downshifts coming to a stop, but not every time.

Second time out, acted like it had shifted into neutral when I came to a stop at the end of my alley. Then, for a block or two, had that slipping clutch feeling.

No issues before I changed the fluid.

Any ideas what might be up? Thanks.

I think that a hard down shift while slowing down is a high idle speed and the other sounds like it still low on fluid. Did you check fluid level after your trip? Hot?

I had 6 qts in at the time. I have since topped it off with a pint but haven't driven it since.

Thanks for the response...much appreciated

i would have started the car, run it through the gears then check the fluid in neutral, did you say you drained the torque converter as well ?? if you did i am pretty sure its gonna take more than 6qts to fill,

My 61 FSM has dry fill at 14 pints.
It's all good now except for the leak coming out of the kcikdown lever hole

That seal is 2 bucks from a transmission shop.
1.Remove linkage and levers from top of trans
2. Drain pan and remove (easier than R&R it from the top, KD makes special tool for this)
3. remove valve body and catch more ATF
4. Get socket or drift and push old seal out from bottom
4a. Inspect seal socket for scoring, use RTV if scored or a special seal is available that extends seal out of scored socket.
5. place new seal into position,
6. put bolt with large washer through seal from top
7. Use a slide hammer on bolt to gently tap, pull seal into position OR use nut and a socket to pull seal in (jackscrew method)
8. reassemble.
Should take car of that leak

On 60-65 "cable shift" 904s, the kickdown lever seal is a "soft seal" w/ no metal frame. (the 66 and up selector seal is metal jacketed seal and the proceedure above out-lines how to change those)

The earlier seal can be serviced from above by removing the KD Lever / washer and "hooking" the old seal with a sharpe pick, to pull it out. (they sometimes just break-up... being "rock hard" after years of heat)

Once removed, the new seal can be pushed-in and the washer / KD Lever, reinstalled.

It is helpful to drop the rear trans cross member and lower the engine / trans assembly in order to get a little more working room.
It is also nice to drain the trans so you don't have ATF running down your arms as you do the work.

Brain fart, didnt realize you were working on an old "double pumper cable shifter"

61V200, did you use the correct trans filter? It should have two large holes for the fluid. The filters for the 66 and newer trans only have one large hole.

OOPS, sorry, just realizedyour '61 does not have the filter, just a screen in the pan. The filter is in the cooler line.

Yes....just a screen in the pan. Didn't find much in the way of shavings so that's a good thing.

I was under the hood yesterday and could see the area above the pan gasket had a purdy red glow to it, so looks like that kickdown is leaking.


It will have to wait another month before I can get some time off from work.

How bout the shift cable entry? Do those like to leak?

My cooler lines are good as I just replaced them with hydraulic line. They were dry when I made that change.

Shift cable has an O-ring as pictured, but I remember mine was a leaker when I got it there too. Not as likely as the soft kickdown though.
