broken tranny housing

[wrongpew]

After having my '75 1.8 involved in a chance meeting with a tree, which broke the tranny housing mounting bracket, I'm wanting to salvage the newly rebuilt (by others) internals and install in another housing. Is this transplant something that should be left to a pro or could I handle it using care and an average collection of tools?

Low on money and luck.

If you mean you broke the dog ears on the rear cover that mount to the body at the rear most mart of the car, quite simple.

By propping up the tranny with a jack, you can remove the rear cover (13 13mm nuts IIRC) and replace it. You will not have to change a single internal anything. Get a new rear cover gasket and perhaps a new speedo gear seal if you are so inclined and go for it. Don't forget to put the grounding strap back on.

You're alright Herb... I don't care what they've been saying about you. BTW, I'm constantly getting the thumbs-up and jaw-dropping from children too.

Herb, will it be necessary to drain the trans oil? Speaking of oil, do you have a preference between Mobil 1 and Swepco?

Yeah buddy. You're gonna need to drain the gearbox oil to replace the rear cover, or anytime you open the gearbox up for that matter.

I like the Swepco 201 80/90w myself, but the Mobil is good too. It's just a matter of preference. I would go with the Swepco, but maybe I'm only saying that because it's one of our featured products

Uh yeah - featured product

You won't need a full gasket kit, but I would get some hylomar and an end cover gasket.

Be careful on re-torquing the nuts, they only need 20-23 ft-lbs. If you need a rear cover, I have some tail shift covers laying around. They look a little funny, but work fine.

Oh yeah, the best way to put the end cover back on and still hold all the peices for reverse in place is...grease...

The washer (with the cutout), slather it with grease and stick it to the intermediate plate. It will hold fine. Now slather the shaft in the tail cover with grease and put all the reverse gears together and they will stick together. slide the cover forward and get the reverse shaft into the washer and the hole in the internmediate plate. The cover will close with a few hammer taps. I hope you put the gasket on first.

Always always always fill the tranny with plain old gear oil ($6.99) on the first change. This way, if there is a leak or a problem, you have not wasted $40 in gear oil. Put the more expensive stuff in (if you plan to) when you do the first change.

That sounds like very smart and experienced advice. James, I may be talking to you again about a Hi Performance rebuild on one of my trannies. We will see how the money goes. Otherwise, I Will be stuck buying a 930 gearbox to install. We both know what that will cost.
