Transmission mission
My 74 XJ Sovereign has a cast iron auto which if you have ever tried to pick one up you will know they are very heavy. And not the best auto you have ever driven either. It so happens I have lying around in my workshop a ZF box out of XJ40 (around 1990 Vintage) which is far better auto and half the weight, but will not fit the XJ motor.
So my question to all you learned Jaguarphiles is, when did Jag change to an alloy casing and can I get one to bolt onto my XJ. I am not concerned if the later box does not have a speedo drive as I have already converted to an electronic speedo. |
you can fit a ZF, but you need adapters.
contact the following company to see if they can help with the conversion, they do it all the time. :: G. Whitehouse Autos Ltd :: |

If you are not looking to do the work yourself the following shops (according to mate in Tauriko,he emailed these links) are the go to places for classic car conversions. Steve Long Automotive is the closest to you, Marshalls is a bit of a hike over those mountains.
But you probably have local contacts already any way. Automatic Transmission Repairs & Servicing - Marshall Transmissions Steve Long Automotive & ADI Towing - Vehicle repairs, wof, servicing & towing specialists. Mt Maunganui, Tauranga, Bop - workboot.co.nz |
We adapted a Nissan 5-Speed & clutch for our project.
There is tons of room for adapters on this engine/ chassis. |
Doug, I think their price includes the ZF tranny, (not sure), but any conversion will run in the thousands, including a GM tranny conversion.

I would hope so....that might explain the price! but any conversion will run in the thousands, including a GM tranny conversion. You're right, but far fewer thousands :) You can do a TH700 conversion for $2000-2500 , assuming DIY labor on the installation itself. Roughly $200 for a used transmission, $600-800 for a local trans shop to overhaul it, $1000 for a conversion kit, $200 miscellaneous. Assuming DIY labor on the installation of course :) Cheers DD |
Thanks Guys.
Thought about doing the manual thing and looked seriously at Toyota Supra 5 speed. Its the dollars that put me off as my wife tells me I am over budget and out of browny points. Getting a conversion for my ZF is probably the best option. Cheers Anarchy |
Supra transmissions are too expensive
The toyota transmission game is a well played & now expensive game.
The Mk.III supra has 2x 5 speeds options thefirst is the W58 (NA tranny) can hold around 320 RWHP & not much more they can be found for $250-$400 The second Mk.III supra tranny is the R154 (turbo version) it can handle upwards of 600 RWHP with a single readily available modification/ replacement to the shift fork. They fetch around $750-$1000 Then you get into the Mk.IV supra transmissions there are 3 variants the 5 speed that is slightly updated version of the R154 that carries the same name, so it's pretty much the same thing. The older 6-speed (V160) handles around 800 RWHP cost approximately $3000-$3500 The newer 6-speed (V161) it's a beast $ well supported & with minor upgrades can handle 1000RWHP, but the price is around $4000-$6000 That's why we opted for the Nissan transmission, it will handle 800+ RWHP (tested in various professional competing FormulaD cars) & costs around $500 or less. We will be premiering our project car this weekend & swap parts are ready for production. |
