MGB Transmission removal

Posted by kodiak

I have a 74 MGB that I need to remove the tranny from. Are there any quirks with a brit car that I need to know about, or is it a straight drop from the engine.

Quicker and easier to remove the whole engine and tranny as a unit. Welcome aboard.

Hi and welcome to the board. With in an hour or two you should get a goodly number of replies to this question. It has been covered may times in the past so use the Search feature to look for 'Engine removal"
To sum up there are 2 thoughts here but the majority will be in favor of the plan than you must remove both engine and transmission together. I just did exactly that recently and it really is not that difficult - although time consuming.
Unless you are really experienced modt agree that replacing a transmission in a car where the engine has not been removed is very tricky.

You may get a masochist or two who will insist that you can remove the transmission with the engine in place. I will simply tell you that I did it that way once before I knew any better. Never again. It may be possible with a non-overdrive transmission, but I found it much easier to remove and install as a unit. That's just one man's opinion.

Of course, there are the real problem solvers that you see once in awhile. Those are the ones that simply take the sawzall to the center crossmember! smiling smiley

Well, you can, however, like you I did it once and will never do it again! The one I removed was an O/D box, makes it a bit harder but it can be done.

Pull the engine, it's not worth the hassle of trying to get the gearbox out on its own.

Joe,
Find and buy a Haynes MGB manual. It will give you step-by-step instructions, along with photographs to help illustrate the entire engine/tranny removal and replacement.
Cheers,
Robert

Joe -welcome aboard and or to the madness!

This topic comes up a fair bit and there are lots of prior threads/discussions on the various techniques, what you'll need etc.

A few to get you started:-

- A titlting device is very helpful to angle engine and tranny as it's coming out.

- Some suggest to raise the rear end of the car to make the angle of extraction easier

- You will forget to disconnect something so if it doesn't come out smoothly stop and check! winking smiley

- Read up on modifying the transmission/rear cross member to make putting it back on WAY easier

- Better to have someone help becasue you'll often need a second pair of hands but it can be done alone (I'm not brave enough)

- There are MANY opinions about connecting the hoist and which points to use. I've gone with the valve covere removed and using those 2 studs. Others like alternator mount and read exhansut manifold stud

A search using "engine pull" as the search in this form for the past year will yield useful stuff.

Good luck and come back to ask as many questions as you need to - this place is great and full of good helpful people!

The engine and trans together weigh a bit less than 500 pounds, so you can use the 1/4-ton setting on your engine. That makes it a lot easier than using the 1/2-ton setting, which necessitates pushing the engine straight back about 8 inches! BTDT.

I have done both.

The drop is not so bad ...

If you replace the clutch while it is out, it can be a real bear to get lined back up as you put things back together.

Just my .02
