fullfuel01 Posted March 1, 2014 Share Posted March 1, 2014 I'm in need of a complete of what's left of a TRDXL10780 mack transmission. it was using the same cassing (or damn close too) of the 12 speeds. would consider buying complete truck. it was in production from 1970 to 1981 in R, RD,Dm etc...it's a 5 speeds, with direct or 'lo' and overdrive on the second stick.

kscarbel2 Posted March 2, 2014 Share Posted March 2, 2014 If this is an on-highway application, did you ever consider a TRDLG1070 7-speed overdrive?

ws721 Posted March 2, 2014 Share Posted March 2, 2014 would you be interested in a TRXL1070? Its completely rebuilt with around 3500 miles on it. It has a .62 overdrive. It's air shift Quote Remember if it's got a hood it's no good!

Vladislav Posted March 2, 2014 Share Posted March 2, 2014 I'm still wonder what a tranny TRDXL-107 or its modifications is?It looked like a triple counter shaft unit.But why it's not one of the T-200 series?

maxidyne237 Posted March 3, 2014 Share Posted March 3, 2014 If this is an on-highway application, did you ever consider a TRDLG1070 7-speed overdriveDont you split just the top two gears? Its just a trdl1070 with the split blocked off right?

skip Posted March 6, 2014 Share Posted March 6, 2014 The gearbox mentioned sounds similar to a TRDXL1070, and a TRDXL107. These were both 5 speed main sections with a high/low section. The TRDXL1070 has a lockout in the compund section which only allows the second lever to be shifted when the main is in 4th and 5th. The TRDXL107 has a lockout in the compound section which only allows the second lever to be shifted when the main is in 1st and reverse. Can someone tell me what the difference is in the gearbox mentioned?

Both are triple countershafts.
