What is every Mack transmission offered from the 50s-1990 (B/R/Superliner Models)

[bamlogisticsinc]

Im noticing a need for shift pattern stickers.

So im gonna try printing some out for people and sell it on ebay. 

 

So what is every transmission (not eaton/allison, MACK only) offered in the 50s - 1990? 

 

Thanks.

i was not sure if Mack made a 13 speed Dave, that is why i did not include it in my list.

You are really asking a lot here. Over the 40 year time span you ask about, Mack made literally dozens of different transmissions.  The number of speeds each transmission had just begins to tell the story. There were multiple gearboxes within each series of transmission, and often different series of transmissions offered in each truck model.

Duplex 5x2

Triplex 5x3

Quaduplex 5x4

correct on the three main groups But within those groups in terms of making dash shift pattern decals are sub groups. a quad 5x4 could have a dash decal of 18 or 20 speed. and so on.

Yes, as said above. 40 years is a large time frame. In late 40's to early 60's and possibly even later Mack had two main families of transmissions - T67 and T72. Both with a single countershaft. Each series conteined basic 5-speed units and with a compound box attached was offered in Duplex (10-speed), Triplex (15 or so speed) and Quadriplex (18 or 20-speed) units. Than in the late 60's or early 70's the next generation with 3 countershafts came on the market. They were basically called T100 such as T105 or T106 for 5 and 6 speed with variations of markings such as T1078 (for 6-speed(!)) and also TRD's for Duplex and TRT's for Triplex. Than later in early 80's that generation was refreshed with newer design T200 series (also 3 countershaft design). Those were T2050 for 5-speed, T2060 for 6-speed and the same way up to T2180 18-speedy unit. Ok, in 90's next gen T300 took place which may be found taking place in later series RD or DM trucks.

Each of those mentioned and unmentioned transmissions had its special shifting diagram plate. In the late 70's and further those were stickers. And in earlier times metal plaques were used attached to cab sheet metal with screws. Also some (probably many) trannies got shift diagrams of different styles during the years and worth to point out every sticker/plaque had its unique part number marked on it since all they were original Mack spare parts.

During more than 10 years I used to keep photo's of every shift pattern sticker/plate I saw on the net or on a real truck. And now I would doubtly count 1/20 of all shift patterns Mack used during those 40-50 years. So what you're going to do is a big deal.
