66rmack Posted November 29, 2015 Share Posted November 29, 2015 Could somebody tell me what Trans has this shift pattern. This is off the heater panel of my dads 66 R model, h said it has a quad. But this doesn't seem to be right for a quad? As always thank you guys for the awesome help you are always giving to some of us newbs. And again sorry for the upside down pic... I can't get it to flip...😡 Quote Link to comment Share on other sites More sharing options...
Apple dog Posted November 29, 2015 Share Posted November 29, 2015 Now that I'm rite side up again it is a 6 speed. Quote This is Mack country. On a quiet night you can hear a peterbilt rust away. Link to comment Share on other sites More sharing options...
Back In Black Pulling Posted November 29, 2015 Share Posted November 29, 2015 no expert but i think it is 6 speed it says to only use low in in first gear Quote Link to comment Share on other sites More sharing options...
85snowdog Posted November 29, 2015 Share Posted November 29, 2015 Its the same as my snowplow a TRXL 107 or 1071 six speed . They are both the same but the 1071 has a low low creeper gear.Hopefully someone chimes in because I don't know if the were available in 1966. So it might be a quad. With a newer heater cover. 1 Quote Keith Link to comment Share on other sites More sharing options...
mrgumby Posted November 29, 2015 Share Posted November 29, 2015 (edited) i remember the old 6 speeds had reverse in the main stick ..if i remember correctly that was in 68 or 69 ..then the newer 6 speeds were that pattern Edited November 29, 2015 by mrgumby Quote Link to comment Share on other sites More sharing options...

Endt675 Posted November 29, 2015 Share Posted November 29, 2015 Hey boys, that's a TRXL 107 for sure. 6 forwards, 5 reverses. Good transmission. Quote Link to comment Share on other sites More sharing options...

Mack Doctor Jr. Posted November 30, 2015 Share Posted November 30, 2015 My dad has one that has R and 1-5 on the right stick and the left stuck was direct and against the dash is over drive. That truck will move out with 4.17 in it Quote Link to comment Share on other sites More sharing options...
220cummins Posted November 30, 2015 Share Posted November 30, 2015 Shift pattern is for a lo hole 6 speed. If it's a quad reverse would be in the main not aux like shown on tag. 1 Quote Link to comment Share on other sites More sharing options...
66rmack Posted December 2, 2015 Author Share Posted December 2, 2015 Thanks guys. Snow dog did nail it. I asked my dad. He said he replaced the heater assembly with a take out. He didn't even seem to know it had the sticker on it. Lol.. Quote Link to comment Share on other sites More sharing options...
cecilktm Posted December 8, 2015 Share Posted December 8, 2015 (edited) If it were a "quad box" it would have 4 speeds on the auxiliary stick, 5 speeds on the main, and 18 usable forward gears total, as 220cummins shows in his post.What your dad's truck has is a "lo-hole" 6 speed, which means it also has a Maxidyne 237 engine, both available for the first time in 1966 (the Maxidyne 300 engine did not debut until 1973)EDIT - I JUST SAW YOUR PREVIOUS UPDATE ABOUT YOUR DAD CHANGING OUT THE ORIGINAL HEATER COVER AND REPLACING IT WITH ONE THAT HAD THE "LO-HOLE" SHIFT PATTER STICKER...... I IMAGINE THAT WOULD BE QUITE A SITUATION IF SOMEONE TRIED TO SHIFT THE QUADRUPLEX TWIN STICKS USING THE LO HOLE SHIFT PATTERN Edited December 9, 2015 by Oil Man Quote Link to comment Share on other sites More sharing options...
Superdog Posted December 8, 2015 Share Posted December 8, 2015 My dad has one that has R and 1-5 on the right stick and the left stuck was direct and against the dash is over drive. That truck will move out with 4.17 in itI tried to buy a '70 R685 along time back that had that overdrive 6 speed,sure not many around,I haven't seen another since. Have seen 2 with the lo hole version,the were set up like a 12 speed,with the aux.stick in lo,it locked out everything in the main box except 1st and reverse.
