Hi All

Progress report, I've got the gear box all apart and everything else looks good. On the parts hunt so far I have found a source of multiple 3rd gears NOS $60 each which could be put on to the old lower cluster it would require press the unit apart and pressing the new gear on. In talking with that source they may have an NOS transmission the whole thing $1200 they are checking to see if they still have it. From another source I found two used transmissions that look fair to good $125 each.

The NOS transmission if it is really available I think is my preference though I will buy a replacement gear for the original box anyway so that it is a complete ready to use unit. With three trucks all sharing the same box having a spare would mean I probably will never have transmission problems again.

Once as this thread has turned out to be more about the transmission and less about the Rally, once I can figure out how to do it I'll move the thread over to the Restoration heading.

Cheers Phil

Always good to have spares, one box for three, sounds like the way to go!!

The original scale of spares lists transmissions at 4 per 100 vehicles per 12 months so on first glance the plan of 1 spare for 3 trucks seems a bit cautious. On the other hand, what good is less than a complete transmission if the plan is to be able to replace the assembly?
Another way to look at is that you are going to hold an 8 year stock (if my math is good) on a scale designed for service driving, use and abuse....... and much longer on your kinder driving, lower mileage and better maintainance program. You should be good for life.

Grant, Phil is scaling, based on a 25 year projection.

Hi All

When I started the thread I thought it would be more about the show and less about broken transmission teeth. But the search for new parts has been quite enlightening. So I requested that it be moved to the Restoration Forum.

Hi All

As of this afternoon a NOS Transmission is being shipped to me from Tim Tygarts http://www.obschevy.com/ of Nashville, Georgia USA. What is a bit strange is that the transmission was purchased by them with a lot of other Chevy parts probably 20 years ago. From the other photos it has only very light surface rust. They had to build a shipping crated to ship it so it will be interesting to see when it arrives.

This transmission was not listed in their online catalog in talking with the people down there they have a lot of parts which they have only a couple of which they do not list. So if you are looking for a particular part it may be worth contacting them. I have found them to very responsive to both phone and e-mails. Yes they do know how and are willing to ship overseas, though they did add the comment that shipping cost out side US or Canada often exceed the cost of the parts.

As I mentioned earlier I also found two used transmissions at Jim Carters http://www.oldchevytrucks.com/ both of them have the same casting numbers as Chevy CMPs. But again they were not listed in their catalog or web site it took contacting them with part numbers and specific request. They likewise were very responsive getting back to me within 24 hours with photos.

I will be posting more detail on this on my web site near future.

Who was it that had a broken transmission case a couple of years ago? Did you find a replacement?

Cheers Phil
