so iv got a xjr6 in my landrover, bolted to a zf4hp24 gearbox, (so its already got the zf adapter plate and bits)

but im looking at a manual conversion, but the getrag 290 gearbox seems really hard to find and when you do, they are really expensive and require a rebuild,

Is there any other gearbox that bolts onto these something more modern maybe a 6 speed?

 

I haven't heard of anyone using anything else since the 290 used to be plentiful enough, but now it seems the market has dried up completely.

I was thinking the new Tremec TKX might be a good option - there are bellhousings available for it that fit the 6L V12, so it should work with the the AJ16S as well since it shares the 4l80e with the V12.
you would need a custom propshaft made though.

 

NV3500 was the licensed built version of the Getreg 290 in the US

Bolt patterns may have been tailored for the engine matching in the US market

New Venture Gear 3500 transmission - Wikipedia

 

if its helps, i should of said im in the uk

 

an old quote i found when googling the 3500

 

There was a resent manual conversion done in the US for a AJ16 supercharged that covers the details.

yes iv read it, as stated the getrag290, is an externally rare box here in the uk now, there is one on ebay 4 hour drive from me in bits, casing and all the rest is loose in a rusty box for approx $500 lol

 

There was a supercharged X300 outside London on E - bay that the owner was parting out that may have the Getreg 290 in it

I'm not sure if it was offered by Jaguar as a factory built manual transmission version for the British Market

 

iv just had a look cant find it

 

I gave the link to Andy Stoddard a few months ago who was on the engine design teem at Jaguar back then

I'll see if I can retrieve it

It was in the northeast corner outside London

 

I can't retrieve sent private message history sent to Andy on this forum from my side.

He would have the received message on his history and may run across this tread and maybe pic up on it

I sent the E - bay offering to him as he has 2 supercharged examples as a potential part resource if he has some things in the works

His ID is " XJREngineer "

 

I've often thought these cars would really rock with a manual, although the ergonomics are a bit funky in the factory shifter spot.

 

Andy has modified the AJ16 supercharger engine ECU to handle the manual.transmission

So work has been done in cracking the code

 

im already running a standalone, MAXXECU with a compushift standalone gearbox controller,

 

This is a normally aspirated 4.0 liter with Andy's bracket for ignition 5 degree advance
