Hi All,

I am in the (long and possibly never ending) process of restoring my 1966 S type, 3.4S Auto.
The engine is out and I am stripping it for a rebuild.
There's not much guidance on separating the engine and auto box in the service manual which only seems to deal with the manual box. I read in the Jaguar service manual that there is a separate service manual for the automatic transmission which covers removal of the gearbox. can anybody offer any guidance or have a copy or a source for this manual? I understand that I want to remove the gearbox and torque converter as one?

 

Yes. Find the bolts on the flexplate ( takes the place of a flywheel) and unbolt the torque converter from the flexplate. The bolts will go from front to rear. I think the only access is from underneath once the access panel is removed, but I can't remember for sure.
You should be able to slide the torque converter rearward a bit to seat it further into the pump. Then unbolt the bellhousing from the block and the whole assembly should come free by moving rearward off the dowels studs in the block. It will be heavy, so best to have it on a jack or other support that you can roll it away from the block.

 

go to my website and to the Manuals page to download the Transmission Service Manual or any other manuals you need.

If you need the full Service Manual go here. Never seen a free pdf.
Late models have BW35 but not a '66.

Many thanks for responses, much appreciated.
I have removed the access panel at the base of the torque converter/bell housig and the securing bolts (which are fitted with locktabs) can be accessed there by turning the crank.

 

So I have the box off with the bellhousing, torque converter and gearbox all as one. I have tried to free the (10) bolts holding the flexplate to the cranksahft. Lock tabs have been bent back.
I have tried a small breaker bar (12 inches) on a couple of the bolts (with another on the crankshaft bolt on the front of the engine to prevent the crank turning) but no joy.
Have looked in the service manual and don't think I'm missing anything, like them having reverse threads for example.
Just wanted to check if there's anything I'm missing before I exert more brute force to get them undone?

Any advice welcome from peoples previous experience with these bolts?

 

They are very tight, but standard right hand threads. I use a Milwaukee cordless impact good for 1100 ft-lbs and they come right off. I prefer an impact over a breaker bar, as then I don't have to lock the crankshaft in place to remove the bolts.

 

in my experience removing a flywheel from a 4.2, I used a helper with a breaker bar and socket to lock the crankshaft from turning, then I used a large 1/2" ratchet with proper socket, and a sledgehammer to smack the bolts free.

then you have the two bronze bushings that need removal near the center. Then it's left to right pulls until it comes off.

 

So applied a bit more force and they cracked open and are off, thanks for the replies.

So now those two brass bushings. Am I right in thinking that I put a long bolt in each hole and tighten to push against the block to force the flexplate off?

 

man I can't remember how I got them off, I think I threaded a bolt and tried to pull them by the bolt head with locking pliers, or I may have tried to pull the flywheel off with the bushings in place. But I know they came off before the flywheel.

maybe you have it right and that is how it works.

 

Use a bolt of the proper thread to go into the bushes. Put the bolt and a thick washer through a socket that is large enough to fit over the outside of the bushing. Then tighten the bolt over the socket, and the bolt will pull the bush straight out and into the cavity of the socket.

 

yes that is how it was done. Thanks.

 

That's brilliant, Thanks

 

A few washers and a big old nut did the trick;
