 Posted: Thu Oct 15, 2015 7:52 pm Post subject: 2nd gear brake band |
 |
|
I made a big mistake of undoing the big c-clip holding on the 2nd gear brake band. It was leaking heavily so I figured I'd replace the "seal" while I had the engine out. Bad idea! I am wondering how to compress the spring enough to get it back together, any ideas?
Thanks! |

You have to back off the 2nd gear brake band adjuster to be able to get the cover back in the hole then slip the pawl back into the band end--then readjust the band with the adjuster screw.
Boing--the spring probably blew the cover outa the trans as soon as you took the clip out---

It sounds like the only proper way to do it is to drop the pan and then maybe I'll see how things are supposed to line up. I hope I can find some new seals, it was leaking pretty good. I don't see any adjuster screw. I'll have to look again today.
Thanks! |

I found some useful threads about the 2nd gear brake. After looking at other posts and reading more, I really don't want to take any more things apart! I guess my two questions are:
Is it possible to put it back in without taking apart the transmission?
Will it be very obvious if it is not installed correctly?
Thanks! |

To properly reinstall the 2nd gear brake band piston you'll have to remove the ATF pan and valve body... just be ready for that. Two reasons for this:
1. to properly seat the piston rod on the 2nd gear brake band upon reinstallation (easy to get it wrong, impossible to do it blind)
2. to use a convenient tool to reinstall the piston (see below).
You can do the job with the AT in the van. You'll need a large 4" vise lock to press the piston into the AT housing while you reinstall the piston cover circlip.

Not at all true, but perform this task within your own ability.
The end of the band can be viewed pretty easy to hook the rod pawl back into it with the pan dropped only.
The key here is to loosen the adjuster up enough to get re-hooked.
Not heart surgery, just the 2nd gear brake band rod pawl back into the end of the band.
I've performed this operation too many times to count, and it's no big deal.
For the OP;
Look in your Bentley at pg 38.7--you'll find the adjusting screw pictured there.
Loosen up the lock nut first then back the screw out a turn or two--or whatever it takes to get the rod pawl back into place.

Does anyone have any pictures of this process? Or is it impossible to see?
Thanks |

Dave is going to have to do some tearing into his trans for his weeping brake band piston seals.
And he is most certainly Cecil B. Demil here.
Perhaps he can document this event for you.

I recently moved and don't have access to my Bently, it's a few hours away. Is that section scanned anywhere?
And the photos were really helpful, thanks kourt.
Thanks! |
