904 slipping?

[Glennster]

My 904 tranny is slipping a little as it goes into second gear. It only does it at high RPM under power. The lower speed normal driving is not a problem.
 I've got plenty of new fluid...........
Is there a cheap easy fix that I can do?
THANKS for any suggestions!

You can try adjusting the band.

How do you adjust the band?
It that some I can do myself?

[tactransman]

Yup.
Loosen the lock nut (3/4 size) right above the front cooler line
run the adjustment bolt in snug (72 in/lbs.)
back it off 1 1/2 turns and hold it while you tighten the lock nut back up.

[Glennster]

I think even a Lug Nut like me can do that!
THANKS again to tactransman!!!!

That thing is a little tricky to get to. After trying many combinations of sockets, swivels and extensions, I got the lock nut free.
 It was about 5 turns in before that bolt got snug. I made the adjustment and took her for a ride. It slips a little more now than it did before.
  2nd gear to 3rd seems like there's no slip.
When I rev it high in 1st and shift to second, it slips for a second or so and then hooks up. But there is a big delay as it's trying to hook up.

Did I do something wrong or it it just too tired?
THANKS for the help!

It sounds like the band is shot. How many threads were showing on the adjustment bolt when it got snug?

[Glennster]

1, maybe 2..................
This is going to be expensive isn't it?

The front band itself is pretty cheap but you should also check if the front servo is ok. I also recommend polishing the front drum if the band is burned.

What is the servo and how do you check it?
Can a rookie like me change the band?
I assume I have to remove the tranny to do that???
I was going to drive to a car show (2 hour drive) Saturday, is this thing about to die on me?
