I have to remove and rebuild my tranny, are there any tricks that may help me? I am no mechanic but would like to try this anyhow!!
 
For the rebuild, be sure to check out the gearbox articles on the Buckeye Triumphs and VTR sites. Good clutch articles on both sites, too.

For removal, best tip I can think of is to get help, preferably from someone with a strong back and a weak mind :devilgrin:
 
And clear out the entire passenger side, seat to carpeting, toss "moving blankets" all over the floor pan.

...and don't forget the wires to the backup light switch. They make a funny "plinking" noise if ya do. :wink:
 
What they said. I just did it, not so hard. I have a small floor jack that I put under trans with 4"x4"x4" on top to reach and a hole drilled in it for the drain plug to keep centered. That should be an even a bigger help going back in.
Now once you get it out........I have everything off on the outside and spent this morning going back and forth between printouts of the two sources TR3driver mentioned to try to get in my head what comes next. Of course first another trip the the hardware store.
 
Just a minor suggestion. When you are finished and letting the car down, don't let it fall on the mechanic. His shoulder will never heal properly.
Ask me how I know!

I borrowed one of these the first time I pulled the gearbox...

Made it easy to get just the right support and still wiggle the dingus around to the right spot.

Later saw it on sale and bought one for myself. Cut the 'ears' off as I didn't need them and was able to install an OD gearbox solo with only minor bruising and lacerations.

The passenger seat suggestion is quite right for your TR6 though (FWIW) for the TR4 I find it easier to pull the steering wheel and driver's seat to exit away from the handbrake.
 
I just took mine out to convert to HDVA. A couple of suggestions:

I had good success using a floor jack with the saddle removed to support the transmission. The oil drain plug fits right down in the hole the saddle goes in. I also put a piece of wood under the back of the transmission between the floorboards. The wood and the jack worked well to slide the transmission back. (No helper!)

Be sure and pull out all the little clips that hold on the screws for the transmission cover around the flywheel. The transmission will try to snag on them.
 
My transmission was a Quantum Mechanics rebuild and it was cleaned like that when I got it.

Randall, we did everything in that article including facing the square blocks in the proper direction and the blocks aren't even shown in there. Mr. Gunst was adamant about how they fit in, but they aren't even in any of these pictures.

I had several email discussions with him (from Germany) along the way and I sent him pictures of each and every removal, so I know that my problem was using it with the Borg & Beck PP, which he and TRF have since stopped selling with the Gunst bearing. He finally stated that his bearing should not be used with the B&B and that was my problem. Judging from these pictures and my own experience, I have to agree.

Too bad no one ever told TRF that in the beginning. Or me.
 
Brian -- don't know how you use your car or if it has an overdrive gearbox, but if it doesn't you might consider a rebuilt OD from Quantum mentioned above by Paul.

I put one in a few years ago and consider it one of the nicest things I've done for myself. Not cheap but what a difference if you take long drives (or even if you don't). This also side-steps the rebuild issue though you could still try your hand at that without having the 6 off the road for any longer than it takes to R&R the gearbox.
 
You might consider doing this

That's a scary picture Frank. Do you have an "I" beam across your garage? If so, that is really cool.

The only good ones are the ones that are going back in.
 
No not a steel I-beam, but I did erect a temporaty "bridge" from 2 6x6 uprights and a triple 2x10, all pressure treated. This was a few years ago and that lumber is now part of my daughter's deck. :smile:
 
I just looked "up"... VERY similar to Franks set-up. A pair of 2x8's glued and bolted, resting on a CB wall at one side and a 4x4 at the other. MGB, Lotus and Alfa engines with gearboxes attached have been yanked out, swung about and reinstalled over the last two decades with that. So far, so good... no deck plans here, tho. :wink:
 
Now that project would definitely get me into marriage counseling.

I can hear it now:

"You told the carpenters to stop working on the kitchen and bathroom to do WHAT????????"
