I have a Packard transmission question about reverse gear engagement. Maybe it belongs on the general forum section, but I'll start here for now.

PROBLEM: Reverse gear no longer works.

It worked for 400 miles after we got this "stray 47 Clipper" on the road several months ago. After backing up in reverse about 75 feet a month ago, it has worked intermittently.
Now it does not work at all.
The linkage feels smooth and reverse SEEMS to be engaging from the feel in the gear shift on the column.

Our mechanic has looked at it. He removed the cover. Everything seems to be in order.

Putting it up on a frame lift with the wheels free hanging, the wheels TURN in REVERSE gear. The reverse gear appears to works.

However, then the frame lift is lowered and the wheels are on the ground, AGAIN REVERSE GEAR does not work.

1. Any Ideas on this mystery of reverse gear?

2. Could it involve the shoe [3.242] on the reverse gear / 1st gear shift fork? [3.240]
See Illustration below.

Does the vehicle have overdrive? If so, check for a failure of the reverse lockout circuit.

Quote:O_D,

Yes, according to it's Registry Entry.

Hello all, In my opinion, if the gearchange linkage is moving the physical position of the Reverse gear into mesh, which I believe that it is doing, then basically the only reason for no reverse drive is that the Overdrive lockout cable has not pulled the lockout sleeve over the sun and planetary gearset in the overdrive unit. Moving the gearshift lever into reverse starts to engage the lockout sleeve but with a bit of wear, it doesn't quite start to engage the sleeve. I would check under the vehicle ( without the engine running and with a hoist or suitable ramps..of course), to see if the lockout lever on the RH side of the OD section is moving fully forward as sometimes the cable clamp may have slipped and the cable is not operating correctly. Good Luck. Peter T

If it does have OD check out the reverse lockout as O_D mentioned. That was an issue caused by the R9 ODs electrical system and was covered in a service article.

There is also another article pertaining to a failure with the lockout sleeve Peter Packard mentions.packardinfo.com/xoops/html/downloads/SC/SL-VOL17NO21.pdf

Thanks guys for all the helpful replies.
This 1947 Clipper is not registered Here on PackardInfo.

The overdrive is not engaged. I think it is disconnected at the solenoids.
This Clipper is my brothers in MO.
I am in SD, so I'll pass on your ideas.
I haven't been to Missouri since the pandemic.

I'll get some photos and register his machine.

You have been so helpful in my 12 years of Owning my 1941 Clipper.

I'll restart our blog soon.

Good afternoon...We're glad you're here...Ernie in Arizona

There are two systems that operate the overdrive - electrical and mechanical. The mechanical system needs to lockout the OD. Good advice here to assure the lockout cable is fully moving the arm on the OD unit. Operating the car in reverse with the OD engaged will cause severe damage to the OD unit.
