No - like this (sideways)

Hi Garry,

Purists will hate this...............but have you considered an auto trans in front of a LT95 TC? Not the BW bodge jobs, but a Ritters C 4/9 conversion from the early 1980's ?

It would bolt straight up to a 3.5 or 4.6 using stock trans mounts and stock driveshaft length. I have had one behind a 350 in a 74 RRC for some time now and really enjoy it.

The advantages are numerous.......... you get the multiplier effect from the torque convertor so it will take off much faster, outright initial cost is minimal because everyone wants a 5 or 6 speed, the workmanship in the bellhousing, adaptor section and the machining of the LT 95 is top notch. The cost of a full reco and bulletproofing of a C9 is less than a grand. A good C 4/9 would easily handle a 4.6 with the weight of a 101.

And it does crawl downhill in low range.

The only downside is that it is better leaving the auto in 1st or 2nd when in low range because it tends to hunt between the gears too much in drive with mega driveline clunks. Only when in low range though.

Thanks - have thought of it but would prefer to stay manual. Also the LT95 arrangement in the 101 is a couple of inches shorter than a normal LT95 so the engine will end up further forward than it is now but that is likely to be a similar issue for a R380 though I would be using a short bell housing so maybe not.

Cheers

Have you considered using an electric or pneumatic solenoid on your overdrive?

It is the way that 2 speed truck diffs operate with the actuator switch attached to the shaft of the main gear stick just below the knob.

I've actually got one of those BW bodge jobs in the shed. Bit long for a 101 even if they weren't crap.
Even if Gary wanted to go over to auto trans, the 101 winch in my experience is not a particularly good match for a torque convertor.
Once when I was recovering a T400 auto equipped 101 that was bogged down to the diffs, the winch rope on my own vehicle wasn't long enough to reach so the 101 owner payed out some of the 101s winch rope and joined it to mine.
The 101s winch has very little gear reduction and depends on a positive connection to the engine to hold the vehicle on a slope when not winching.
The big Chevvy 454s torque convertor at a fast idle (2000rpm) couldn't provide enough resistance, and the pull from my winch only succeeded in unwinding his rope, even though his winch was also attempting to pull. We worked around this problem, but I'd imagine there would be some winching scenarios where this would be a PITA.

Only passing but is a good option - would be Ok changing into O/d but when changing out (essentially changing down a gear) may be problematic. The O/d is fully synchronised but like many gearboxes it requires a slow movement to not get ahead of the synchros - I normally double shuffle it when changing down which works well (mostly). If I changed down without double shuffling the movement is so slow that I immediately need to also change back from 4th to 3rd on the gearbox (unless on the flat) as you loose too many revs.

The type of change suggested would be OK engaging but most likely too quick when disengaging but obviously I have not tested it.

I've forgotten all the different permutations, but is there such a thing as a short Lt77/R380 to V8 bellhousing?
Your short 101 housing could be bolted on to an R380 with a sandwich plate.
Or how about fitting a complete short bell R380/Lt230 and fitting a right angle drive onto the output shaft of a vertically clocked Maxidrive winch PTO?

AFAIK Ashcrofts only make the short Bellhousing R380 kit for the 200Td1. The one to ask would be Dave Ashcroft "Ashtrans" on this forum.
