Geoff Weeks Posted yesterday at 04:47 PM Share Posted yesterday at 04:47 PM There is an SST-2 12 speed, I haven't found any lit on it however. Still one of Spicer's selling points was fewer movements of the stick. This was on all their transmissions. I wonder what one you guys are thinking of?

mowerman Posted yesterday at 05:27 PM Share Posted yesterday at 05:27 PM I just did a quick Google search myself. I couldn’t find anything on it either. I’m supposed to be outside taking out a steering box. Can’t seem to come up with any ambition.

Geoff Weeks Posted yesterday at 05:40 PM Share Posted yesterday at 05:40 PM From you 1995 reference, it would be much newer than the Spicer's I'm thinking of. In fact I think by the late 90's Spicer's heavy transmission were sold of to TTC? That was around the timeframe of "semi-autos" and auto shift manuals. I thought you two were talking about much older transmission, like late 60's. One place I worked did maintenance on a mixer fleet that had 6-71 and the Spicers in a Ford chassie. I never owned a Spicer equipped truck, but would have liked the late model 16 and 18's, nice even spacing between gears, and few stick movements.

mowerman Posted yesterday at 05:58 PM Share Posted yesterday at 05:58 PM Yeah, this was a 1995 Volvo white. You’re probably heard me mention a time or too. I ran a 237 maxidyne 6 speed I hated that thing I would’ve been pissing myself to have anything else in it, but the six speed Bob 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75514-mastering-the-art-of-shifting-a-10-speed-transmission/page/3/#findComment-576021 Share on other sites More sharing options...
mowerman Posted yesterday at 06:00 PM Share Posted yesterday at 06:00 PM Besides the 237 would not pull your hat off and a wind storm as far as I could see, they were designed for flatland mixers, and trash trucks Quote Link to comment https://www.bigmacktrucks.com/topic/75514-mastering-the-art-of-shifting-a-10-speed-transmission/page/3/#findComment-576022 Share on other sites More sharing options...
Brocky Posted 23 hours ago Share Posted 23 hours ago GW: The one I drove was in a 1962 Autocar snub nose with a Cummins.. The shifting procedure was also in the Drivers Manual for my 1959 Diamond T 921C which had a 220 Cummins. I cannot post a picture of the manual as I gave it to the man who bought the DT. 2 Quote Brocky Link to comment https://www.bigmacktrucks.com/topic/75514-mastering-the-art-of-shifting-a-10-speed-transmission/page/3/#findComment-576035 Share on other sites More sharing options...

Ok, two different transmissions, early 60's would be a single countershaft, likely married unit, much different than what Mowerman is talking about and different than the twin countershaft units I know. I do remember Glenn talking about some trans with an air shift cyl external and IIRC required a pass through neutral. Before my time/experience. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75514-mastering-the-art-of-shifting-a-10-speed-transmission/page/3/#findComment-576036 Share on other sites More sharing options...

There was indeed a 12 speed Volvo with what appears to be two switches. Problem I had was the Facebook video I found ??? was a guy in Zimbabwe. I have no clue what he was saying, but .... 🤔 Zim Bob way Mowerman.....

Old 8000 series. Seems back that early it would've had two sticks. Later ones ( like an 8716 or 8512 ) had an air control that resembled one on a 12 speed and if I remember correctly were usually blue (?) I remember someone seemed to think they were a great transmission....if you were a guy who fixed transmissions for a living. 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75514-mastering-the-art-of-shifting-a-10-speed-transmission/page/3/#findComment-576040 Share on other sites More sharing options...

They were a real treat in an older truck . Nothing like dust and oil for clevises and pins. 8000 series I think. If you had one that was "married" they were around 4 or 5 feet overall length.

Adkat Posted 31 minutes ago Share Posted 31 minutes ago Hey Bob, Reckon if it was anything like our Aussie Volvos it would have been an SR1400/1700 Volvo box, full synchro, clutch every gear and to split. Air assist clutch so wasn't too hard on the leg.
