Getrag 360 speedometer cable
Hi All:
I'm the proud new owner of an olddie but goodie 1989 D350 dually with the 12v Cummins diesel. When I got it the speedometer was not-operating. I checked it and I discovered that it wasn't connected to the transmission.
I crawled under and hooked it up to the transmission but now it runs backwards!!!
I think the transmission may have been replaced and I'm not sure it's a Getrag since I have no experience with them at all. It IS a 5 speed and otherwise works and shifts fine. The stick has been broken off and re-welded back on but I understand that that is common.
Does anyone know if there is an easy way to put this right so that the speedometer runs the right way?
Thanks
Edwin

The speedo is not cable driven, it uses a speedsensor or at least on a 93 4x4 it is. If yours is the same it may be he put the wrong stuff in or tried to convert it.

If the transmission case is all cast iron, then it is probably a Getrag, and it will have GETRAG cast into the case.
If it is an NV-4500, then it has an aluminum auxilliary casing and tailhousing.
I have never heard of the shifter breaking on either of these transmissions, but
The later trucks use an adapter gear-box in the speedo cable -- maybe you need a similar unit? Also, the later trucks use electronic Speedos, so direction of rotation is not important -- you still get the same number of pulses per minute no matter which way the exciter gear is turning.
Interesting problem -- let's see what other folks say.

I was hoping that there was an "adaptor" missing and that the transmission wasn't running backwards. It shifts fine but it has a little low speed noise in 4th gear until the rpm's are up. I assume this noise is the gear teeth slapping when the engine pulses and not some problem brewing. Hopefully somebody will be able to point me to a source to the adapter.
I was also hoping that perhaps there was a different hole or connection for the speedo cable that turned the other way. Yeah I know, things are never that simple.
