Has anyone successfully fitted a Gertag 265/6 transmission in a Series 1 Coupe?
I am about to replace the engine frames on my 67 Coupe and figured this is about the best opportunity to fit a 5 speed transmission. About a year ago, I installed a Getrag 265/6 in my 250SL Pagoda and I just love it. I have another one just waiting to go in the E Type, if it is at all possible, without butchering the car.
Your advice will be much appreciated.
I think I got the message, LOUD AND CLEAR.
My understanding is it’s a bit difficult and cutting required……. Better idea….change the diff to a 2.88 and enjoy the pleasure of not looking for longer legs …the car is still very spirited in the lower gears too
I did the change on a Series 2 . But I think there shouldn’t be any difference . The installation was straightforward , just a little bit of cutting at the gearbox tunnel where the gear lever comes out .
But you need a lot of parts to make the Getrag ready to fit . If interested look at www.limora.com , part number 337099 . Additionally you need a clutch driven plate and a prop shaft .
I kicked it out after 10.000 kms , for me the 1. and the 2. gear ratios are too low for the high torque engine , I installed a 5 speed gearbox from Classicfab with standard ratios for 1. - 4. gear and 0,63 for 5th .
If I’m not mistaken, isn’t the Getrag box a 1:1 (or close to it) in top gear?
If so, it seems you’d still want a 3.07 or 2.88 final drive to make the car enjoyable to drive, so it would make sense to do the diff swap first, and then decide if the gearbox swap is still “necessary”.
Not as I understand it the 5th gear is effectively a reduction to less than 1 which can be achieved using the taller diff
my Getrag 265 has 1 : 0,78 gear ratio , but a Getrag Sport 265 has 1 : 1 in the 5th .
Hi Chris a.o.
A Getrag 265 is almost the online 5 Speed Box that fits in a Serie 1 without cutting ! This because its length .
As a Hobby I sold several of this Gearbox sets for the Mk2, Xk, and E type , last one really this week for a S1 , Consist of box, adapter plate, pilot bush, centre disc, chromed shifter and special tachometer drive for our jaguars. Further of course a new flange at the rear.
As I am in the Netherlands, will shipping of the parts be to costly , but if you want pics send me a pm .I don,t know how to do this here in the threath.
By the way : unless a sport box ( final 1:1) have all Getrag’s out of the BMW an overdrive 5th gear.
A 0.78 OD would be nice in something like an MGB, but in something with the torque of an E-type, it seems like you’d want something more like a 0.68, no?
So, back to my previous comment, it seems like anyone with a 3.54 would still find themselves wishing for a 3.31 or 3.07 ring and pinion even with the Getrag.
why do you not use a T 56
ratios: 2.66, 1.78, 1.30, 1:1, .80, .63.
Rodger, thanks, I would appreciate some more photos,
Thanks for your input. I have a 2.88 diff installed.
For the record, the Getrag 265/5 is a 5 speed close ratio transmission, “dog leg” first gear and 1:1 5th
The Getrag 265/6 (Rodger’s photos above) is the overdrive box, normal 5 speed H shifter pattern, a 1:1 4th gear and 5th with an “overdrive” ratio.
THIS IS THE ONE TO HAVE.
As mentioned above, I have installed one in my 250SL Pagoda and love it.
Why would you have a 5 speed with a final ratio 1:1 ? Not needed when you have so much torque and using the 2.88 gives you the long legs
I think that is quite viable: my '63, with a 3.07 behind the stock Moss 'box, never wanted for low-end grunt, even at 4300 meters.
Continuing the discussion from Getrag conversion in a short wheel base XKE:
Apologies guys, I accidentally erased my previous post. However, for easy identification I will try to post a photo of the Getrag 265/5 close ratio transmission and the 265/6 overdrive unit.
