Once I finish rebuilding the rear end, axle, diff, and rear brakes, I would like to tackle the trany next. I still have the rear brakes to rebuild and the entire axle rear end to paint, but once I am done with that I want to yank the trany and rebuild it. So since the stock 3-speed trany is still in the truck and attached to the 223 I-6 engine, what is the correct and easiest way to remove the trany considering that I will be working on the ground and considering that it is still attached to the truck and the cab is still on the truck. Please lay out the steps that I should follow when removing the trany?
I have a good jack, but is it worth getting one of those trany trays that Summit sells which mounts to your floor jack? Please advise. Thanks in advance.
reminds me of an old comedian on the radio who used to call people up on the phone and antagonize them till they wanted to fight him... and he'd say "well... just how big a boy are you ?"
In my younger days I've done chevy 3-speeds without a jack. I'l add here that "out" is much easier than "in". I'm assuming you mean floor jack when you said you had a good jack.
Before I'd invest 50-100 bucks in one thing I'd never use again... I'd weld a short piece of pipe (with an o.d. close to my jacks pad) to a piece of scrap plate..;pull out the jack pad and insert your newly made support and use that... barring welding skills/material I'd just center the jack pad under the body of the transmission ...most of the weight is in the case... unbolt the trans from the housing (don't forget the speedometer cable) and of course the drive shaft from the trans. and wiggle it back a little. A screwdriver prying on each side of the housing will help move it back... sometimes they get a little stuck. Take your time. It helps to have a 'jack' man helping you move the jack/trans back as you pry....but you can manage it alone.
When the shaft clears the pressure place and housing... let it down and drag it out...
I'd make sure I had my truck up high enough to roll the jack/trans out and stable enough to take a little jostleing. Good jack stands are better than concrete block.
Now putting it back in will try your patience trying to line everything back up.
Make sure any of those tray attachments fits tightly in the hole on the jack, and is positively retained with a cotter pin or clevis pin. My son bought one at Harbor Freight and it didn't fit tight, and didn't go thru the jack's plate enough to put the pin in. As soon as it got a little off balance, the whole shootin' match came off the jack.
Heck, it looks like a small enough trany that I could probably just hold it in my hands without a jack.
On BonusBuilts, we have to lift it out thru the floor opening, and I haven't ever used anything but brute animal strength They weigh about 75 lbs., I'd guess. I'd hate for one to fall on me (or you!)
Perhaps that is too heavy for me to be wrestling underneath the truck by myself.
Ok so back to the original question, what areas on the trnay do I need to unbolt first, remove first, etc before I can actually drop it out of the engine? So is it like 4 bolts, and then a big tug and it comes out? Just looking for an overview of the process.
100 pounds sitting on the floor - 250 sitting on your chest - 350 hanging from your finger tips.
Is the rear of your engine bolted to motor mounts?
four bolts from tranny to bellhousing.
remove one of the top bolts - take it to the hardware store and buy two bolts that have the same threads as the original bolt but are three times longer - take them home and cut off the heads - screw one of these in the top hole where the original bolt came from - remove and replace the other top bolt. Now you have guide pins to slide tranny off and on with.
Remove bottom two bolts - speedo - drive shaft.
place jacking device under tranny - barely make contact with jack.
wiggle tranny back and off guide pins while trying to keep jack under tranny.
KEEP BODY AND ALL ATTACHED PARTS OUT FROM UNDER TRANNY AND JACK.
Hey Dick. Thanks for the reply. Yes the engine and trany are still mounted/bolted to the truck frame. I guess I could go ahead and rip off the fron tend and yank out the engine and trany together at once, but I was hoping to just play with the transmission for now.
