yea you would have to turn the drive shaft 4.1 times to turn the tire once. 3.55 turns to one tire turn would be 3.55's

 

thats it. i was close.

 

No LSD on this one. I probably will end up changing that damaged gear as well as re-gearing if needed, but I'd rather hold off if it's not that big of a deal because there's a whole laundry list of stuff I need to do on the truck (ie. Shocks, tires, tranny flush, ball joints, tie rod, etc.). So if you guys don't think that the small broken piece is gonig to cause the whole thing to fall apart in the next 5k or 7k miles, 'just rather hold off and take care of it if and when I decide to re-gear.

 

Don't do a tranny flush on these transmissions, I've read a lot that people say it does more harm than good. I'm sure someone else will chime in on that or do some searching.

 

If you still have the cover off, the number of ring gear and pinion gear teeth or the gear ratio itself is usually stamped into the ring gear. Ring gear teeth divided by pinion teeth equals gear ratio.

 

Ive been told by several people not to flush these trans. Better to drop the pan and ajust the bands, clean up the govenor pressure sensor solenoid thingy and do new fluid and filter. Sound about right?

 

Okay, I dropped the pan and cleaned everything out. I adjusted the bands. The rear (inside trans) required very little adjustment. The front band (outside trans), which apparently needs to be thightened to 72 in/lb took almost 3 full turns to get to 72 in/lb. Now the head of the adjusting screw is almost flush with the edge of the locking nut. Does that seem even remotely normal? I don't want to overtighten and ruin the trans. The truck did have a tendency to slip in the lower gears pretty regularly before I did the work. I don't know if it has ever been adjusted, and it does have 180k miles, but it seemed like a lot of tightening to get it to the right torque. I don't really want to drive it with this doubt in my mind.

 

Yeah, the band friction material wears off, so, tolerances open up. Also, it isn't really a direct relationship with how far the bolt moves, and how far the band moves...... you are attempting to reduce the circumference of a circle.

So long as you back it out the right amount, everything should be golden.

 

My manual is in the garage - so just shooting form the hip here - but I think after you tighten front band to 72 in lbs, you back of 2 7/8 turns.

I have not noticed any rear end noise (but I do not have good hearing). While I had rear drums off I spun axle and rear end sounds dry. Got gasket and will pull cover off tomorrow. Hope there aren't any loose pieces there!

 

I'll take a second look tomorrow morning when it's not so dark and cold out. I'll also drop the pan again since I haven't filled it yet an make sure I did the rear band correctly.
Can someone explain to me the purpose of backing out the screw after tightening? Is it similar to a brake drum and shoes in that you need to leave room for things to turn freely?
