Hi, I’m looking at a supposed (1967 E type) used 4 speed
Transmission with OD for my 2+2. I’ve read the posts on the
forums here about the OD models and also searched Google for
the serial number on the model I’m looking at. The overdrive
looks compact and the ratio is a 28% reduction according to
the first few digits on the tag. Does anyone have information
on this unit? Thanks!

I thought I read some time ago that an Overdrive unit will not
fit into an E-Type?–

Hi Ben,
Jaguar fitted the 28% Compact A Type OD behind the standard 4 speed
box in a variety of its saloon cars. Never originally fitted to E-
type, but will phyisically fit with standard propshaft in a 2+2 or
S3. If you plan to fit the box as a whole unit, do check that the
clutch actuation is as you expect, the later cars switched from
slave cyl on bellhousing pushing back to slave on gearbox casing
pushing forwards.
You can pull the mainshaft & OD from your donor gearbox and rebuild
it on the end of your original gearbox to get a ‘matching numbers’
car with OD…i did that for my S3 (mainly because the clutch
actuation on my donor box was wrong for my later car).–

Hi,
Yes, it will fit (lengthwise) any LWB E-type, but no SWB.
Jos, was your car originally manual?
I had no trouble fitting it (once I had changed the gearbox
top cover from the XJ6 type to the E-type version) but my
car was originally automatic, so the tunnel was wider.
Actually this also made it easier to change the solenoid
later and changing the gearbox oil from under the car.
I knew the manual cars had a narrower gearbox tunnel, but I
thought it was only in the bell housing/ torque converter
end and not in the other end?
Cheers,
Pekka T.–

It does.
I fitted a 1969 4-speed + OD from a XJ6 in my 1969 2+2. Jos Raven PA0AMX
No problems except quite a lot of work adapting the tunnel.

As David said, you need to look for the ‘‘Compact Type A’’ overdrive
as the length of this unit is exactly the same as the length of
a ‘‘long tail’’ Etype gearbox and BW autoboxes, as fitted into the
long wheelbase cars. There are plenty of older overdrive boxes
around with even longer tails on them - these don’t fit without a
shortened propshaft and I don’t know anyone who has even tried to
fit one.
If you look at the first two pictures, you’ll see the part of
the ‘‘long tail’’ in the first picture and the top of the ‘‘compact A’’
OD from the XJ6 saloon in the second picture.
But I had to open up the top of the tunnel to widen it a bit as
visible (sort of) in pic #16
Then again, I think if I had made the cut a bit lower it would not
have been necessary to do the cut.
I could have made the new top to fit properly.
The shifter came out at the place of the automatic one.

Hi Guys,
It’s always great to hear how knowledgeable everyone is on here. I
need to measure the unit I’m looking at to make sure it fits. It
appears that the automatic that I’‘m replacing in my car is approx
27.5’’ from the end edge of the bell to the post on the rear of the
gearbox where it rests. I plan on measuring the transmission I’m
looking at this evening. The real question I had for everyone was
trying to identify this OD unit- it very clearly states ‘‘E’’ for the
unit type on the serial number plate. I haven’t been able to find
any information that an ‘‘type E’’ overdrive exisited.
I had thought these overdrive units were inmpossible to find in the
states and never really looked into it back when I was planning the
switch to manual. I have since found a good ratio in an early
camero V8 T5 and am pairing it with an S-10 transmission tail
shaft. I will probably go the T5 route after reading some old
forums on the pros and cons of each- although I do have a
completely restored moss box w/syncromesh that I had initially
planned on using and now that I’ve found this overdrive set up I’m
tempted to go original. I realize my 2+2 isn’t all that valuabe
compared to the other XKE models… is a T5 more valuable in a
restored E type than an original working overdrive with a
syncromesh gear box?–

If you have the chance of a t% I’d use it. The OD is good but a
solid gear is probably better in terms of durability if you use the
car very hard. For the street it’s fine.
But you MUST ascertain the legnth is correct. The Compact type A of
the right size was only fitted to XJ6 boxes AFAIK. There was a
Compact Type A fitted to the post 65 Mk2 all synchro cars but the
tial housing is a fraction longer than the one on the XJ6.
I think from memory the length you need for the basic box and OD
is 19.5’’ from the front monuting face of the box to the rear face
of the output flange.

having owned several cars with that overdrive unit I can say that
it was always a pleasure to operate and near bullet proof.The old
healeys had a lot of relays involved but Triumph and Volvo cars
didnt bother with them as far as I recall. My TR6 overdrive has not
relays and it opertates in 2nd 3rd and 4th same as my 100-4 Healey.
I think once you have it installed you will love it. 150MPH?–

I was following this thread and I had contacted the guy who was selling the unit last week. I was out of state at the time, but I stopped in to see it yesterday and decided to buy it. I have no clue on what shape it’s in. I assume this is the same one being discussed.
There is some sort of resistance on turning, so I’m hoping it isn’t like one I saw on a website that was totally rusted and pitted on the inside.
It does look to have an overall length of 19.5". Is this the length for a 2+2, and thus no way for a convertible?
A side note. I was heading to see the unit and came upon a distressed red e-type on interstate 85 in Georgia. I pulled over with him to give a hand. It was a beauty but the ignition was acting up. The consensus was likely a condenser and the owner got in touch with Dick Maury. I also noticed the carbs were about bottomed out with no oil. I don’t know if that could have contributed to the issue. Anyways I’m sure Dick got him back in action.

No good for any short wheelbase car. ‘Convertible’ includes long
wheelbase so not an answerable question. Be a pity if you can’t use
it but the original poster needed it. I can help in any event but
still…

Hi there,
I have fitted a mint MOD box from a Mk2 340, to my 67 Series 1 2+2.
I did a lot of reading first, then measured the heck out of
everything. I have saved the original motor & auto box, replaced it
with a very warm 4.2 pushing around 350 H.P., coupled it to the all
syncro box, fitted it to the car with very little modification. I
have the same box in two other Jags and enjoy them, superior to the
Moss box in my Mk2, but retained in my Mk2 for originality. From
memory, the only alterations undertaken were a slight mod to the
tunnel for the speedo drive, a modified rear gearbox mount (taken
from an S Type & the original retained) and a shortened drive shaft
(the yokes also sacrificed from same S Type I have dismantled. The
hardest part was obtaining an original clutch/brake pedal box,
although I had worked out if I was stuck, I could modify my
existing and add a clutch pedal. The car is nearing completion from
a total restoration, has been driven (illegally) and is yet to be
properly road tested, suffice to say, once rolling goes like stink
and will leave my V12 for absolute dead! I am about to replace the
2.88 auto diff for a 3.54 (I have a couple of limited slip spares),
as first gear is way to tall and like taking off in fourth gear! I
obtained a manual tunnel cover and modified to fit my car. I have
made no mods to the interior console and utilised the existing hole
in the console for the gear stick. As the car was a matching
numbers car, I have retained everything and able to return the car
to original specs if necessary with out modification. Things are a
little close around the tunnel, but all is good. So, yes can be
achieved without too much hassle, from my experience!
Regards,
Rob–

If you put in a 3.54 you are likely to be very disappointed,
with 1st and in particular 2nd gears being far too low. The
3.07 is by far the best compromise and was used by the factory
in RHD 2+2s–

I am pulling a Chevy v8 & atuo box from my 1970 2+2. Just
installed new frames from Etype fabs and putting in a
correct 4.2 and manual conversion. Does anyone know the
‘‘correct’’ location for the shifter? I have a modified
bellhousing for a T5 box. A T5 box with an S10 tail puts the
shifter 11.5’’ from the face of the bellhousing but it looks
to me as though this is going to be a little too far
forward? Any wise words gratefully received!
Thanks!

I’m the unlucky guy who didn’t get the overdrive. Any chance it’s still available? How come it didn’t work for you? I have collected a fully synchronized 4 speed already and I’m weighing the cost/effort in doing the T5 route with a 5speeds.com bell-housing. Thanks, Ben
