Transmission question.
A friend of mine and I got into a discussion about Ford transmission synchronization. I was under the impression that Ford did not use Synchronization until 1939 and then it was a full synchronization. He said it was not synchronized in first gear. I was reading Mac Van Pelts site and it appears 2 and 3 were synchronized beginning in 1932 and improved in 1939. What is unclear to me is, was 1st gear also synchronized in 1939? This is what I thought. If 1st gear did not have synchronization in 1939 when did Ford introduce it?
Thanks. |

Re: Transmission question.
I had a new 63 Fairlane hard top with a 260 3 speed, it was either a first that year, or the previous. Paul Selfe.

Re: Transmission question.
I'm not familiar with Ford model A, or Ford transmissions after the mid 50's, but I know '32 thru '53 pass. car and light comm. vehicles had synchronized 2nd and 3rd, but 1st/rev. were not synchronized. '32 to '38 (maybe some early '39's) did not have the additional brass syncro rings. '39 on up has the improved synchronized system for 2nd and 3rd, with the additional brass rings. I'm not sure when Ford began using synchronized 1st/rev. in their three speed standard transmissions.

Re: Transmission question.
As an owner of a 39 coupe, I can say for fact DD is correct. 39 was for 2 & 3 but not for first.

Re: Transmission question.
Most late model modern manual transmissions are synchronized in reverse these days. As far as I know the 5 speed Tremec and BW of the 90s were the first rear wheel drive types to use a reverse syncro.

Below are pictures of a Borw-Warner (Tremec) T5 reverse gear. The first picture is REVERSE "UN-engaged". The second picture shows REVERSE gear "engaged". Would you care to point-out EXACTLY where the synchronizer might be for reverse? I'm almost hearing Al Borland saying..."I don't think so, Tim!" DD |

Re: Transmission question.
There are modern manual transmissions with a synchronised reverse, but not all. Whether 51% or more modern transmissions have it, I don't know, so whether saying "most" have the feature is correct or not is difficult to prove.

Re: Transmission question.
REALLY!
Below are pictures of a Borw-Warner (Tremec) T5 reverse gear. The first picture is REVERSE "UN-engaged". The second picture shows REVERSE gear "engaged". Would you care to point-out EXACTLY where the synchronizer might be for reverse? I don`t have a picture handy but the Tremec T45 Was a reverse synchronized trans used in the 90s. Also the TR3650 was a revised version produced later. The trans in your pic is a T5 and is not synchronized in reverse.

Re: Transmission question.
Ford first went to a fully synchronized 3 speed trans in 1963. I was in high school and Ford donated 3 of these transmissions to our auto shop. Almost immediately, one kid beat on one trying to take it apart and it became replacement parts for the other 2. In 54 years of working on most all makes and model of car, I have never seen reverse synchronized. Maybe I've lived a sheltered life?

Re: Transmission question.
If there is only one speed in reverse why would it need a syncro?

Re: Transmission question.
For me too, it was a surprise to find some gearboxes had synchro'd reverse. Getrag transmissions from Germany are used in many performance cars and at least some of those have the feature.

Re: Transmission question.
I've got a couple of manual transmission Audis with synched reverse, not that I'd really need it. It just makes shifting easier overall.
Also, I know that some later T5s (World class?) had a reverse brake that acts like a synchronizer by keeping the gears from freewheeling. https://cobratransmission.com/images...nchro-cone.JPG |
