band adjustment

Gidday,
Is anybody able to give me instructions on how to adjust 1st gear bands to (hopefully) stop slipping in 1st? Its a C4 in a 71 F100 Ambo.
Thanks
Kel

I would check with the gang in the Trans forum, but I did the adjust on my C6 and it's quite simple. There is(should be) a threaded rod with a screw driver slot on the side of the trans. Lossen the hold-down bolt and twist in the rod. I would go 1/2 turn at a time and see what you get.

A C6 has only one band, for 2nd gear. To adjust it, loosen and back off the lockdown nut on the square-headed bolt on the left side of the trans, tighten the square-headed bolt to 10 ft. lbs, back out 1 1/2 turns and lock the nut back down.

Follow the same procedure to adjust the front band on a C4.
For the rear band on the C4 (low/reverse), follow the same procedure as the front band, except back out the square-headed bolt 3 turns.

C4 slipping

Gidday instig8r63,
Thanks for your response.
There are 2 adjusting bolts, one on each side of the tranny. Do you know which one is the first gear adjuster?
Thanks
Kel

The adjustment toward the rear of the trans is the low/reverse band, the one toward the front is the 2nd gear band.
Hope this helps.
Good luck!

C4 slipping

Gidday instig8r,
As I havent done this befofe I just want to confirm your instructions. I wind the adjuster all the way in and torque it to 10 ft, then wind back out 3 complete turns? Is that correct?
Thanks Mate
Kel

10 foot pounds on the C6 band

Would 120 inch pounds be the same as 10 foot pounds? I've got a torque wrench that doesn't go any lower than 30. However the inch pound wrench might can do it if I have my numbers right? Anyone know?
