when I let the tranny jack down, the engine didnt even Move hardly at all.. the bus suspension move a tiny bit..

Oh I better get the thread updated with progress and pics.. the Tranny is Bolted in!!!

I think I have most of that. Not sure what "cruise thru city traffic" implies. My tranny temp gauge (almost) worries me. It comes off the left needle and moves otherwise I would seriously worry. My gauge starts at 100. I don't think I've seen it above 125. Engine temp gauge reads just left of center. I've seen it go as high as just right of center on a climb. Don't remember the gauge numbers. Just left of center is what the bus depot guys said it should be.

Here we go!!! ive been busy with work like crazy.. trying to release a new software cloud product and build a school bus at the same time.. as well as deal with a **temporary** roomate who is using me badly.. has made for me being behind on my updates of this thread!.


I knew I was going to need some TOOLS!! to get the job done... Thanks to ECCB for the tip on the HF 20 ton bottle jacks.. these things ROCK! and they dont lose pressure overnight either..

First stop!



Sercond stop I was going to need an engine hoist to be able to move the transmission around.. so I booked a "portable engine lift" via my local sunbelt rentals and off to get it I went.. by the time the paperwork was ready, it was in the bed of my Trusty old (new) Silverado.. I got home and HOLY CRAP.. portable??? really?? yeah it weighs more than me.. (im 140 lbs)... well after all what good would a hoist be if it couldnt hoist itself in and out of the truck! so I rigged it up to do just that!..

this pic was later.. I deleted the original by accident.. grrr.. anyway you see the shiny tranny in this one.



Now I needed to get the old transmission out of the Bus and somehow on the ground..
the first part was easy... i got out my trusty HF tranny jack.. (Ok my original was red and beat form years of hotrodding.. I loaned it to a friend a year ago who seemed to be MIA when I wanted ot get it back.. so I got a new one.... so if anyone needs a tranny jack.. yeah I got a newer one..



then i just started taking out all the bolts I could find around the tranny.. and unplugging wires.. I drained out about 5 gallons of nice red fluid.. it reallty didnt look like the fluid you would expect from a Defunct transmission... it was nice clear and pretty.. all except the very bottom of the pan which is expected..

put the jack under it.. and I strapped it to the jack with an 800 lb ratchet strap so that it wouldnt go anywhere.. then I took out the converter bolts.. I used a BIG screwdriver to spin the engine a couple gear teeth at a time.. and found that on the front (toward front of bus), about halfway up is an access port for a ratchet to go in and unscrew the nuts on the torque converter.. I put some axle grease on the inside of the socket so that way the nut wouldnt fall out when I too kthe socket out of the hole. (sorry the access port pic is missing!..

here is the jack under the trans, ready to get it outta here.


Notice the second strap to the left.. yeah I'll tell you about that one in a bit.. the challenges of working under a LOW suspension Bus...!!

to help with getting the bell bolts loose there is a plate in the floor that gives you access to the top bell bolts.. I took these out LAST.. in case all H*LL broke loose the tranny would fall to the ground harmlessly with me not under it..



more to come!

I set up a backup strap on the transmission as even strapped to the jack I was worried it would fall out of the bus frame and something would break.. so I strapped it in the front to the bus frame.. this way I also knew that the front wouldnt tip forward.. i wanted the converter to come out WITH the trans and not stay up in the engine... this part is important as a 50 lb torque converter going rogue can create big time injury.. as well as damage the flexplate and spill LOTS of fluid on the ground..

after all the bolts were out I horsed and pulled until kablam! it pulled away from the bell, things shook and wobbled but nothing fell and I quickly lowered the tranny jack only to realize what i knew already and that is that it was NOT gonna slide out from under the bus on the jack..

an interesting thing is this Ring.. its an extender ring for the torque converter.. it has studs and is bolted to the flexplate.. and the normal converter bolts go into this ring.. YES!! you BETTER use LocTite when putting the inside bolts in.. if you lost one of these you have to pull the transmission to replace it...




so I lifted the transmission with a couple ratchet straps.. big ones.. and then I pulled the jack out from underneath.. so the transmission was supported by set ratchet straps.. the trans jack now went under the parking brake drum where i lifted it as a point higher on the trans.. and disconnected the rear ratchet strap. then I dropped the rear to the ground... next I took the trans jack to the front where I tried to lift the trans via the bell... no dice.. too big.. grabbed the car jack, and lifted the trans at the bell and went up top and released the ratchet strap from up above... then I could go safely from the front of the bus and release the car jack which let the trans to the ground!!!..



hello 20 ton bottle jack.. lifted the rear left ocrner of the bus a few inches.. which caused the air suspension to go flat on the right side.. nevertheless I dragged yanked and kicked and screamed at the old trans till it was out from under the bus!!.

into the silverado and home where I could have it to use for reference.. and to remove parts I wanted to transfer to the new transmission.
