Re: Slipping out of 3 rd on compression
"The needle bearing cage that was provided in the transmission rebuild kit was too long for the input main shaft and it pressed the input shaft forward a bit which didn't help with the engagement of third gear."
Are you using Ford PN A7063 the main shaft spacer ring? Tom Endy has cautioned about not forgetting this... Brattons and Snyders show that their shafts, gears, and roller caged bearings are USA made. Possibly others too but I do not have the catalogues

Re: Slipping out of 3 rd on compression
Yep, I used the main shaft spacer ring with Ford's original needle bearings. Mac's transmission kit didn't use the spacer ring as their needle bearings were too long to start with.

Re: Slipping out of 3 rd on compression
Some shafts have the ring built in, so if you add an extra spacer ring, you could be in trouble.

Re: Slipping out of 3 rd on compression
Certainly glad to hear this!!
Did you notify the supplier that they sent you defective parts? "The needle bearing cage that was provided in the transmission rebuild kit was too long for the input main shaft and it pressed the input shaft forward a bit which didn't help with the engagement of third gear." you went thru a lot to figure this all out......

Re: Slipping out of 3 rd on compression
Before blaming the kit, are you sure the kit came with 2 short bearings and 1 long bearing?
Short = A-7118 and long = A-7121 The cluster gear takes a short and a long bearing, and the input shaft takes the other short bearing. |

Re: Slipping out of 3 rd on compression
i used the Mac's kit with no issues, and really glad I did - our transmission was almost entirely scrap! Luckily the case was fine - all the gears, shafts and bearings were well knackered, and I'd recently already rebuilt the shift tower anyway.
It's a joy to drive now, whereas before we were having issues with jumping out of 3rd at the most awkward of times, and prior to the shift tower rebuild, it was jumping out of second too.

Re: Slipping out of 3 rd on compression
While trying to sort out my Model A parts pile, I just torn down 10 model A transmissions and I was surprised with the differences that they had between them. Like Tom said, some require the spacer ring on the main shaft and some don't. Some require a thrust washer at the front of the cluster gear and some don't. I even had one transmission case that didn't have the four 5/16" NC holes drilled and tapped for the input shaft retaining sleeve cap screws. Out of the ten parts transmissions, I was able to save four complete transmissions. MY shortage were transmission cases. Now that I have recent experience of what goes where, I see that Mac's sent me two long needle bearings and one short needle bearing, instead of being sent one long bearing and two short ones. Not knowing that the longer bearing didn't belong between the input shaft and the main shaft was my error. My old input shaft to main shaft bearings were a gravel pile so I didn't know how long they were really supposed to be. I was smart too late. I should have know better.
