101 Gearboxes (LT95)....

burrt has a gearbox fault on 2nd gear. Going up the box is fine,
coming down it is impossible to select.

Towed a trailer to Towcester, and was able to get 2nd coming down the
box a fair bit of the time.

Took him out today without the trailer and guess what... unable to get
2nd coming down again......

Have thought about a 4 speed auto to replace it, but took the trailer
out with a 4 speed auto rangie today, and the gearbox was forever
hunting, which kind of put me off. With the LT95 in burrt I didn't
have to make many gearchanges at all.

The place where we had the trailer serviced also said that his TD5
Disco kept hunting while towing it.

Trailer is the GLASS exhibiton unit, about 2 tonnes in weight and slab
fronted.

Thoughts??

I'm assuming that the 2nd gear synchro is baulking - I'd try a change of
oil in the gearbox. I'm sure someone with experience of LT95's in UK
conditions will be along shortly to make a suggestion of the best
lubricant to use.

IME, you get used to "playing" the autobox after a while. and see also
Badgers recent post about altering the lockup point for the torque
converter.

You can stop it hunting between 3 and 4 by locking it down to 3 until your
road or speed lets it stay in 4 reliably.

Or, of course, you can disconnect the kickdown cable and use it as a
clutchless manual - note, I imagine if you do this wrong (i.e. let it sit in
4th at 20 mph under load) it'll overheat. I did try it once and it works
quite well - it shifts up at minimum revs if pout into D and will hold any
of the lower gears on the shifter, or go into them if the roadspeed is low
enough. If you have a brainfade and shift into "1" at 45 nothing will
happen, it'll not downshift to 1 'til the speed drops to about 30. Talking
RR 3.54 axles, here, so with 101 axle ratios it'll all happen at lower
speeds, including the TC lockup.

Given a reasonable amount of nouse on the part of the operator, I can't see
this can cause any longterm harm. However, it does prevent you from doing
the "most fun" bit of an autobox motor - pootling in top at about 45, and
flooring it so that it jumps straight down to second and takes off with
mucho impressive engine noise.


Note: If any of you with ZF4 boxes play at "clutchless manual" mode by
disconnecting the kickdown cable and the box subsequently breaks, don't
blame me. It didn't break mine, but I decided I didn't like it and went
back to "normal" mode.

Didn't help last time, to be fair.

Other fault, from memory - put it in reverse,depress clutch and it
still won't roll backwards downhill. Put it in neutral and it rolls
fine.

Warren didn't have any clues either...

Don't discount the Torqueflight 727 auto box. I think that they would
be better suited to 101s than the ZFs, are stronger and simpler as
well. With any autobox however you need to make sure the engine is up
to it as well, they will all sap a little more power.

Not suprising, depends on what, where and how you tow - expect to use
the shift lever to manually select your gear unless you know the
vehicle shift patterns well enough to avoid unexpected changes.

If you do fit an Auto then I'd suggest trying to seek one out which has a
viscous coupling instead of diff lock in the transfer box. I think such a
thing exists though I'm not sure in which model. Our 1990 Rangie TD had
viscous lock but that was a manual. It's one less lever to have to faff
around with to make fit.

My 1994 rangie has auto with viscous lock but as far as i'm awear you need

'89 on range rover, fitted with borg-warner chain-drive transfer box and
viscous coupling.

a nice thing, IMHO, although it's prone to get sloppy when the chain and
gears wear and there's no scope for having different t-box ratios.

The viscous unit can fail either free (won't lock up) or solid (locked too
much), and is about 250 notes to replace.

I dissed the Borg Warner idea when looking at going auto in Grumble
for just these reasons.

TBH, the wear problem is no worse than any other transmission. If you think
you might want to change ratios, that's another story.
