Can anyone identify this transmission?

[Diesel_Gypsy]

Hello all

This is OLD, so I'm hoping one of you "experienced" guys can identify it.

This tranny is in a 1947 TDH-3610 bus. It is a 2-speed automatic with the angle drive after the transmission.

The lockup for second gear isn't working and it seems to be hooked up to fuel pressure to operate it. 

Anybody got any ideas??

Thanks for any help you can give me.

Ya, I thought it might be a Spicer, but I haven't been able to find any info about it on any searches I've done. Not knowing a model name or number makes for a lot of web pages to sift through.

Thanks. . .

It's actually a model 91 Spicer hydraulic drive. single speed with a lock up.

It's not a true automatic, it's built more like a simple hydrostatic tractor transmission. I may have some books on it around here someplace, and possibly the parts pages from a master parts catalog.... give me a few days and remind me.

I one in a 1948 TDH3610....

Hi Jim,

As "Dallas" noted, it's a Spicer model 91 tranny.  It's actually an air-shift tranny.  Keep an eye out on ebay for a maintenance manual.  They're usually listed under something like "Yellow Coach" Model 90-91 Transmission Maintenance/Repair Manual.  I've seen them on ebay on a surprisingly frequent basis...approx 1 or 2 every month.  If you'd like an actual original copy, I had a few manuals that were complete, but a bit "shop-worn", and I gave them to Ted Campbell at Coach Maintenance.  He recently did the powertrain for a customer's 3610/3612 with the same tranny.  I went on the road test and you would swear it was a standard VH-9 power-shift tranny.

Good luck! - Steve
