46RE Assembly of main case

Back to the bench we go. This time with a 46re, this transmission came in for a slipping in second complaint. During the rebuild procedure we have installed a lot of new parts. Total parts description will be below. While most of the transmission has already been assembled this video still follows the basi principles of assembly for the unit.

Though this video does not show every step it does show some very key points in the assembly of the transmission. Some of the key points are proper clutch orientation, gear train stacking, final transmission assembly.

The 46re transmission has been a favorite of mine for quite some time. One of the most interesting qualities of the 46re is the hydraulic circuitry. While the base of the unit has not change a lot over the different generations, the hydraulic circuitry has. This version has a electronic governor pressure sensor that communicates to the vehicle computer and allows the upshifting and downshifting. The vehicle speed sensor aids in this process as well. Hopefully in future we can show a complete valvebody assembly. Thanks for watching.

Awesome sir. Is transmission parts are hard to come by now.

So I had my trans back together and then I read a comment on another video where someone said the reverse band is basically directional. Is it true there's a top and bottom so to speak? I don't see a difference

[garyrichards]

Great video. One question, do you give the clutch plates a soak in transmission fluid on the final assembly.

What's the front pump seal part number? Torque converter seal

After I torque the pump the input won't turn I pulled the band and drum back out to make sure it's all in all the way it looks to be in all the way. However if I remove the pump washer it bolts in and the shaft will turn. Is my pump washer to thick?

I have a 03 Mustang gt with a 4R70W, it feels like if it’s goes into neutral and the rpm’s just go up until I come to a stop then it’ll eventually hook onto 1 gear the shifts are definitely a bit harsh, no fluid is leaking and no codes are being read. I’ve gotten opinions to just do a full rebuild but don’t want to if that’s the case any recommendations?

Would your drill bit clearance trick work on the baby transmissions such as the 42re?

if he is not showing correct clutch clearances why watch
