Green Dash Posted April 29, 2012 Share Posted April 29, 2012 I gonna guess but will not be responsible for inaccurate information A 5 speed direct in 1975 should be a TRL 1076 or 1078. I'm not sure what the difference is between the 2, but Mack made a bazillion of them.

j hancock Posted April 29, 2012 Share Posted April 29, 2012 Slide under the truck on the driver's side and there is a flat pad in the case where the trans info will be stamped. Might take a minute to clean it so it can be read.I try to write info like that in a small notebook and keep it in the glove box if needed in the future.Jim Have somebody with you in case the truck flips over! 1 Quote JimIt doesn't cost anything to pay attention.

Rob Posted April 29, 2012 Share Posted April 29, 2012 Being a tractor originally of disrespected R model origins I'd think it is prolly a TRL107 series. I've seen the TRL 1076 in an R model tractor and it did not have a PTO driving gear, and neither did the 1078 series I removed from an F series cabover. Both of these other transmissions are readily adaptable for the gear, just not installed factory from my observance.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

If I dont let you guys know, im prolly squashed underneath the drivers side door.Go under the frame rail and raise up beside the transmission, or look up at an angle.Although the wheels are still on the ground be certain to use jack stands on the left side for safety's sake.Rob 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Green Dash Posted April 30, 2012 Share Posted April 30, 2012 Now you know why the use of the word tranny raised some eyebrows. To anyone with knowledge of motor vehicles, a tranny is a transmission. To everyone else, it's a transvestite. I still call it a tranny.
