Warner T-9 question
I am cleaning up a 4 sp crash box that was given to me by a fellow barner. I have owned a lot of them over the years, but never worked on one. In the schematics I can see on my screen I can't make out all the small parets. My question is do they have a replaceble oil seal at the end of the shafts? Doesn't seem so. Just a slinger or something? I will be swapping the pickup truck mount for a big truck mount soon and seems a good time to renew the seal. If so, part #?

Re: Warner T-9 question
Which shafts are you referring to? There is no seal at either end of the countershaft or the reverse idler shaft. They are machined with a slightly larger diameter at the rear ends of each. That creates a very tight fit at the back of the case. We just spread some sealer at the front of the countershaft pin.
The shift rods in the shifter housing don’t have seals at either end. The ends are closed off with expansion plugs at the one end only (the detent ends I think). The later T9 transmissions have a regular oil seal for the output shaft.

Re: Warner T-9 question
Thank you both! It is a later T-9 I think because it has the bolted on mounting bell. Is the seal pressed into the rear mount? I guess I'll see on Saturday, but would be nice to get a new one coming. Is there a part # that my napa store would recognize?

Re: Warner T-9 question
I will pull the big truck rear mount off a junker trans I have. I can see it also has a pressed in rear seal even though it has the half bell cast into it.
Thanks all, GB

Re: Warner T-9 question
That sounds like the Canadian version with the cast in half bell. These transmissions were throw backs to the 1930s. They made them with few changes all the way up into the 50s. The reverse interlock control is the way to tell if it's an older one or not. Ford used the T8/T9 design for near 20 years.

Re: Warner T-9 question
I think reverse lockout went away after 1942.

Re: Warner T-9 question
My two cummins generator engine conversions in old ford trucks required GM sm465 granny low four speeds because that's how there were set up for UPS trucks. Well I just had to say they are very hard shifting. Downshifts into second seem the worst. They just don't wanna glide into the next gear. These T-9s shift like silk once you get used to the method and the facts of life surrounding a good crash box. And who doesn't like that nostalgic gear whine?

Re: Warner T-9 question
They all had a reverse lockout mechanism. The early version had a little trigger finger release just under the shifter knob. Those were also obvious by the skinny rod that ran from the trigger down into the shifter tower. On the later version they did away with the trigger and designed a spring loaded release into the part of the reverse shifter rail. You knew you were headed into the reverse position because of the spring tension on the shifter lever as you moved towards the reverse position.
