New Transmission Question

I was driving home from my company Christmas party the other night and my driveshaft u-joint blew up causing the drive shaft to punch a fist sized hole in the transmission as well as some serious damage to the passenger side footwell. So now the question is what to do

a - purchase a used tranny
b - buy a rebuilt tranny
c - not sure if there is a c but if someone has any ideas I'm all ears.

Any known pros and cons of either would be helpful to help with the decision.

Also, if I go with plan a can I use a ZF out of a disco or is there something special about the Defender auto box.

Any idea on pricing would be great.

Thanks

A zf trans out of a disco will work great. Find the cleanest, lowest mileage one you can. I replaced mine after a failed service from the PO. I paid 850 for it back in 2003 and have never had any issues.

RoverLand Parts has great prices and the units are rebuilt, 6 month war. and prices are very low. I just purchased a unit last week paid 1095.00 for a ZF-4hp22.

Did you get the
Heavy Duty ZF autoboxes

Wondering myself if I should go the auto box when I install the 4.6, and bet that it should be mated to the heavy duty version that Ashcroft sells or if RoverLand can get this too.

You really want to make your 110 an auto? I would think the 4.6 mated to the r380 would be awesome to drive. Good power

No, but ZF auto boxes make a daily driver much nicer. The ZF is a really good tranny.
Kevin at RoverTec was asking if I was sure that I didn't want to conver to an auto when he puts in the 4.6. Tempted because of how much I liked driving my 97 D90. Plus if RoverLand has them for those prices I am really thinking...

As long as yo do it right and get the right console. I think the ashcroft NAS style console is much nicer now than it was. I drove a 4.6 97 and it seemed ok but nothing special to me. It might be that I am used to driving a 5 speed which just seemed faster to me. Obviously none of these are fast but I would think the 4.6 in the 110 would make up a bit for the extra weight and make the stick a bit more fun.

last time I checked Ascroft was out of stock on the auto console and I cant speak for RoverLand but I dont think they offer the stronger internals on the ZF.

You would need the correct bell housing and flexplate/Flywheel for the 4.6 engine.

would the ZF from a disco work with the 200 or 300tdi also just to be as specific as possible?

The diesel auto box(internal)is different than the V8's due to the harmonics generated by the diesel. It'll fit and run for awhile. D1 or RR Classic box will work fine with the 4.6 and have no issues. I would recommend putting in a larger tranny cooler than just the tube style or radiator type. If you really want some "ZOOM" try putting a 1.6 T-box behind the ZF. The 1.4 box is fine but for anything larger than a 31in tire the 1.6 is the trick to wake up everything.

Digging up an old thread...

Trying to decide if a $3K up-rated ZF from Ashcroft is worth the squeeze over the $1K ZF from RLP? I'd like some feedback from anyone with a "Stage 2/3" 4.6 conversion...think that is in my near future. For those of you who have a RLP's ZF, how's it holding up? Do you still have the clunking into reverse, leaking?

The clunking is not coming from the tranny! Check the rest of the driveline for wear and the suspension(ball Joint).

I'm aware of the multiplied effects of worn joints, bushings, t-case, etc. Looking around, it seems like some folks are still living with chunking even after addressing these problem areas. I'll be address all the bushings, joints, and suspension components here shortly and see if or how much that helps the problem. I can live with the chunk as long as I'm not stranded in the middle of the Idaho wilderness in 2 feet of snow in November.

I will be addressing the drivetrain sooner or later, and that is where my question was really directed. If I can't get a completely chunk free ZF, but it is able to take 280/350 HP/TORQUE for at least 100K, then I'd be alright with that. But, if I could get strength AND chunk free, I'd pay the $2k extra for that alone. Hopefully, the RLP ZF is able to handle the extra power AND be relatively chunk and leak free, but that might be wishful thinking.

BTW, per the board's recommendation, I've been coasting into stops in N to mitigate the chunk which is 90% effective as long as I coast for 10 feet or so. I still get chunks off heavy throttle or downhill and that annoys and worries me. Off road in tight spaces, no such luck...
