Going to replace the transmission on Saturday with one I got from Manny. Will remove the tranny with the FD in place as Manny says he does. Seems
pretty straight forward. Also fabricated a hoist just like the one Manny uses.

Any other tips from those that have done this job in the past is most appreciated!

I'll post some pics afterwards.

I’ve only done it at the same time as the engine. With a transmission from Manny.

Labeling where the bolts came from makes replacement much easier. A
separate baggie for each location with corresponding label written on. Also
a short screw driver like pry bar helps with lineup during replacement.
Also good to have one person inside working the come along while a person
below guides it. Just don't be in the drop zone.

Make sure no one has welded a bung on the front of the motor oil pan in that little 1 inch gap between the FD and the oil pan, front left corner. Ask
me how I know. It won't go back in as one piece if you have one. The PO put it there for the oil temp sender. I pulled my FD before I pulled the
tranny and didn't notice it till it was going back together and it turned into a 4 hour job after it got bound up. Also turn the steering one way or
the other all the way, that little bit of clearance means a lot on the front of the final drive. Just experiences.

Bob Dunahugh just did the same operation and might have some notes on this site. Search for posts beginning with "Restoration". I know he was glad to
have a second set of hands to help out. His phone is 319.521.4891 and I'm sure he would be happy to talk fine points if you need help m

Jon,

Ken Henderson did a drawing of a lifting bar to raise and lower the transmission with a single point lift.
I can't find it. I will talk to KenH about it tomorrow.

The important thing (at least one) when reinstalling is to not let the torque converter slip forward on the shaft. If the transmission does not slide
right home, do not try pulling it in with fastenerd because if the TC has become disengaged you can do an immense amount of damage.

Jon,

I'm sure you meant by "with the FD in place" that the FD will NOT be
unbolted from the axles and engine. Comments make me suspect not everyone
got that.

You may want to try my lifting device:

www.gmcmhphotos.com/photos/g5741-th425-lifting-device.html

We used it for 4 more R&R's week before last during and after Manny's
visit. Works great.

If you can figure how to locate it, a 1-1/2 to 2 inch hole beneath the
covering on the lower cockpit step riser, in line with the top left rear
mount bolt, is a terrific time & frustration saver. Use a socket and
extension through the hole. Put the hole saw plug back in the hole with
caulk and a slightly larger metal plate when you're done.

We also used the gasket guard shown in that album.

JWID,

Ken H
 
I did an R and R by myself many years ago. Took me at least 24 beer and a
whole lot of time. Did trans and FD at same time. It was a SOB of a job
and I'm not talking about another brand of motorhome !

Ken, are you saying it might be easier if the FD is or is Not attached..

Tks

The FD makes it a wee bit front heavy. plan on that. You'll need a strap around it to level it out more easily.

Mike,

Manny does NOT move the final drive. The transmission can be moved to the
rear far enough to disengage from the FD. IF the rear motor mounts (2
bolts) are loosened from the cross member enough to allow the rear mount (3
bolts) to tilt out of the way.

Thanks guys for the suggestions. I'm well into the R/R. Did most myself but a friend is helping me this afternoon to hoist back in place. I did
make the same hoist set up Manny did based on his instructions and some pics on the photo site. Works really well. Instead of using a chain I used a
strap which I think is a mistake because the trans is not level when lowering and will be the same when raising. If I used a chain then I could hook
in such a way the trans would be closer to level. What I will do is when hoisting back into position I will get it high enough to get my floor jack
in place thus leveling it out. Should have it back in and bolted up later this afternoon.

Looks like you're well on your way! Hope it goes in smoothly!
Replaced mine this past winter and it was relatively easy. I spent far too long trying to get to bolts blocked by the driver's side header before
giving up and removing it. After that - all went fairly smoothly.
http://www.gmcmhphotos.com/photos/g6923-1977-manny-trans-install.html

Getting the coach high enough to slide the trans out was a bit scary for me - and things would have been much easier with a helper to work the come
along. I used a tow chain - securing the grab hooks in the bell housing port using some helpful advice from this thread -
https://groups.google.com/forum/#!topic/gmcnet-archive/4hFaGNKfk3Q

Just got back from a 3000 mile trip to Montana and was very happy with the Manny rebuild, I'm sure you will be as well :d

Finally got enough time to finish the transmission replacement this weekend. In fact finished it on Saturday. Definitely not a 3 1/2 hour job. I had
it ready to come out in 3 hours, this included removal of the drivers side header to get to the infamous bolt on the FD that is hard to get to. It's
a snap with the header off. Also with the header off all around access is easier. Add another 5 or 6 hours to put the new one in including flushing
out the trans cooler(s), I have an aux cooler. Speaking about flushing out the trans cooler(s), I was thinking how best to do this and I ended up
using a high pressure (20psi), in-tank fuel pump, and submerging it into a gallon jug of mineral spirits. Then connecting the output of the pump to
the transmission out line I backflushed the coolers into container. But first I blew out the lines with compressed air pushing the fluid out of the
lines and coolers. The transfluid was full of metal particles! After that I pumped through the first gallon of the solvent which pretty much cleaned
out the lines and coolers. I pumped another gallon through for good measure and blew the lines out with air.

All in all a real PITA job I hope never to do again, especially since I mostly did myself. Did have some help hoisting up in place which really saved
me some time. Test drive went flawlessly and no leaks. Previous tranny had the Ragusa pan which leaked but liked because of the trans temp sensor.
Being that Manny's trans pan isn't leaking I don't dare touch it! Might put it back on after the first filter change.

Thanks everyone for your tips and advice. Proved very helpful.

If I saw metal particles in what I flushed out of the cooler I would
replace the cooler.

Those stacked plate coolers do a good job of disapating heat, and a lousy
job of having millions of places inside them to hide crap. I know this
sounds like slamming the barn door after the horse has left the building,
but, if I saw ANY metal stuff come out in a flush attempt, I would block
off the integral radiator cooler, and replace the additional remote one as
well. You should be able to flush the lines well enough to re-use them. S
and J engines has revised their warranty policy. If remote coolers are
re-used after flushing, their warranty is null and void.
Just what I do.

Jon,

I laude your efforts to clean out the coolers, however, I would suggest you consider the following information:

http://www.gmcmhphotos.com/photos/showgallery.php?cat=6805

As you can see they are like Thomas's English Muffins - full of nooks and crannies! However, in they don't catch butter they catch
nasty stuff! ;-)

Transmission filter photo:

http://www.gmcmhphotos.com/photos/transmission-filter/p57602-filter-2-cut-away.html

I tried to find the micro rating for this filter without success, so the following is PURE supposition. I suggest you try and find a
company in your area that has the Hot Flusher System and have them clean your radiator and remote transmission oil coolers. See if
they'll flush your engine oil cooler as well. You may have to make up adapters to connect their machine to your radiator fittings.

Thanks Rob,

I might have made it sound like large amounts of metal (in size) in the fluid but really it was very very minute particles suspended in the fluid. I
seriously doubt any of these particles would be caught inside the coolers. But for sure you have given me some doubts so I am going to take a sample
just to be sure nothing is suspended in the fluid.

Thanks again,
Jon
