yes sir, but my re-building knowledge of eatons an meritors is weak, with the exception of 10 speed back boxes. However, Mack transmissions where one of my many skills when I worked in the Mack Dealerships. Thats all i got..

in the Mack transmissions, the speed gears have 2 thrust washers in the middle of them, held in with a snap ring. one washer has splines on the inside diameter, that engage the main shaft splines, the other washer has large teeth on the outside diameter that engage the clutching splines inside the speed gear. that thrust washer is to keep the sliding clutch at the proper depth during gear selection. The speed gears that are back to back of each other on the main shaft have a ground surface on the back sides. these gears are thrust against each other. snap rings on the main shaft keep these gears from sliding up and down the main shaft. the sliding clutches are splined in the inside diameter, and are slid over the splines on the main shaft. when this is assembled, as GW said earlier. the countershaft gears keep the speed gear centered. the main shaft is centered by bearings on the ends. the front one being a spigot bear engaged into the input shaft. the speed gear from front to back are as follows. 4th-5th-3rd-2nd-1st-rev... my post is from my head and not my books, so there's a chance I left something out.

and?? I may have missed something here.. sorry GW.. even though I was a tranny builder for Mack years ago, I have lost some memory. So I say its best that I drop out..

Eaton and Meritor have 2 counter shafts... i guess its what year range is the subject.

I like Vlad's idea of some filing.. Atro makes a lot of suspension parts. Take a look at hier line and see.

Sorry, i just realized you posted TRL 107.. dumb me.....

Freightrain, didnt you have a TRD 72 transmission? As far as the 107 ratios, what transmission model are you wanting info on. I have books...

They are typically mounted below the left windshield, in a visible spot standing next to the truck. Its a small black metal box with a row of L.E.D. bulbs to read to monitor the health of the system.

Is there a pressure switch under the hood near the tractor protection valve. The switch that controls that function of the lights staying on untill air pressure is above tractor protection, is a normally closed switch. Any chance you installed a normally open switch by mistake?

I posted a picture that showed the different torque for different stud sizes. 250 is a bit steep. I had to dig through my books. Thanks Paul

CBS news just said that southern border crossings are down 90%. Its not even in the full heat of summer yet... Well, this is a good bit of news.

I hope the info is what you need.. have you checked the tracking on the book i sent ?

An A.C. or M.H. or C.L.

Amen!
