Re: Trans pushbutton units

[Robert <r.lane@xxxxxxxxxx>]

Hi Gary (& others), thanks for the replies.

Well, what it is...
After a few suggestions from the good people here on the list, my brother & 
I had a go last weekend to try and get our pushbutton & cables lubricated & 
adjusted. We got the unit out from behind the dash, but hanging down, still 
attached to the cables. As I said before, the cable retaining brackets had 
been bent over to keep the cables in place. As Paul L pointed out, the FSM 
says the bracket(s) would need to be pried open, but the spindle that the 
cable end was attached to had also been swaged over. So we thought we'd try 
what we could to get the unit lubricated and the cable adjusted without 
separating them completely.
With all the pushbuttons removed from their actuators/levers (or whatever 
they're called), the levers moved freely enough in and out. There didn't 
appear to be anything wrong with the unit in this state of dis-assembly, so 
we put it back in the dash and refitted the pushbuttons. After a few pushes 
of the neutral & drive buttons they started working. Sort of. Occasionally. 
Buttons would get pushed in, but wouldn't always latch in, and wouldn't 
always unlatch the one that had been latched in. The 1st & 2nd buttons would 
hardly go in at all. At this stage we weren't sure if this was a problem 
with the unit or just down to cable adjustment.
Next job was to try the FSM method of adjusting the gear selector cable. 
This involved removing the screw that holds the adjuster in place, backing 
off the adjuster a few turns then pushing the cable in until it locates in 
the reverse detent (at least, that's how I remember it being worded). Then 
the adjustment was done by screwing the adjuster a set amount to line-up the 
holes. This was all supposed to be done with the reverse push button 
depressed. But we forgot this small (?) detail so ended up not knowing 
whether it had been adjusted correctly. At this stage we tried the buttons 
again but they still didn't select properly - sometimes we'd have no buttons 
latched in, and other times two buttons latched in.
So we'd gone from an occasionally sticking neutral-drive change, to not 
being able to select a gear and not being sure what gear the trans had been 
left in!
Next suggestion (thanks Ray) to try was to drop the trans pan to get a 
better idea of what was going on inside, but by now I was already in the dog 
house with the missus, so had to leave that job for next time.
I still think we should be able to get over this problem with a bit more 
tinkering and getting a look inside once the pan's dropped, but when my bro 
suggested looking into whether new/recon pb-units are available, I thought 
I'd start making enquiries.

So that's where we are now. Pretty frustrating as you can imagine. 
Especially as we've hardly begun to see how our newly rebuilt engine 
performs. I'm hoping we can get some help from either the guy that rebuilt 
our trans or the engine builder that put the engine & trans back in the car, 
but I think they'll be reluctant to come out to where the car is. Still, I 
live in hope.....
