1975 chevy c/10 400/700r4

I have the truck on stands in the garage some 2 feet off the ground. I have the tranny jack, and flywheel turner.

What is the procedure to start removing the tranny?

Pull drive shaft
Disconnect linkage
Remove spedo cable
Remove any electrical connections
Remove and plug cooling lines
Remove inspection cover
Remove converter bolts.
Remove top 4 transmission bolts.
Put jack under tranny pan
Remove cross member and transmission mount
Remove remaining 2 lower transmission bolts
Separate transmission from engine

You also may wnat to support the engine so it doesnt lean back and hurt the distributor. You can usually slide a block of wood between the engine oil pan and the cross member to support it or use a second jack.
The other option would be to pull the distributor but this can be problematic if you are not sure how to re-install it.
You may get fluid out of the tail shaft also. Be sure you have a catch pan ready. Also make sure the torque converter is free from the engine. After you unbolt the 3 bolts you should be able to slide it back into the transmisson a little.

If it were me and you have a large enough pan, I would take an extra few minutes and drain the pan to keep the mess at a minimum.

First make sure it's safe to get under it..Then remove the drive shaft..Undo it from the rear end.Put it out the way..Then undo the torque converter bolt's.Make sure you undo all of them..Then undo all the lines and cable's.Then set the jack under the trans.Make sure the motor is blocked were it will not be hanging on the mounts.If not it can cause other damage to other things.Like the rad.etc.Make sure everything is unhooked..Once you double check everything.Undo the bolt's holding the trans to the motor.At this point you better have the jack under the trans.. :pain: Once the bolts are out.Pull back the trans.Once its off the motor.Carefully let it down.Make sure the converter stay's inside the trans.If not Be ready for some fluid.. :pain: Don't think I missed anything,But if I did someone will Bring it up.Hope this helps you out.Going back in is a little different.. :)

Chet. You beat me to it.. :thumbup:

I havn't done one in a while but.............get another person to help, disconnect driveshaft, plug trans. tailshaft or tape a very heavy plastic bag tightly up against it (so it doesn't leak).

Disconnect all the lines and linkage to trans., place a floorjack with a small piece of 2x6 (so you dont ruin the pan) under the engine oil pan. Unbolt the torque conv. from the flex plate, get the trans jack under it and remove the trans mount and crossmember ...if you can, makes it much easier.....then start removing the bellhousing bolts.

You'll have to lower the trans jack and floor jack under the engine a little to be able to wiggle it out. BE CAREFUL, it is heavy, if it gets off balance and starts to fall...it will fall. I think thats about it, oh yea, have plenty of shop rags or paper towels on hand just in case........Good luck.

How about removing the tranmission trans fluid level dip stick, and, doesn't the 700r4 have some kind of electronic lock up that I have to disengage?

Do I need to disengage the kickdown at the carb, or can I uninstall at the tranny, or both?

I've heard about having the torque converter staying with the tranny....could be a MESS!

I have already unhooked the linkage, speedo, e-brake. Was going to get the the oil coolers, and kickdown, but thought to write to get some info on whether to drop the tranny to make it easier for those to uninstall.

All wires will need to be disconnected.

You can pull the dip stick with the tranny or remove it once you get the engine bolts out. One of the bolts tah connects the engine to the transmission also holds the dipstick inplace.

You do not need to "dissengage" the lockup converter.

Disconeect all linkage at the transmisson, there is no need to disconnet both ends.

You should pull teh converter with the transmission.

Disconnect everything before lowering the transmission. Most of these items are easy to get to. Once the transmission is loose it can sometimes be difficult to keep the transmission steady enough to safely get them disconnected.

I think I covered all your questions

You pretty much covered it!

Got the driveline off, just took the tourque converter bolts off (there were 15mm bolts up in there!), and was in the process to disengage the cooling lines (really difficult to get to), and the kickdown linkage.

Thanks.

I will post soon. Should be close to being done for the day.

Drained the tranny, unhooked the oil cooler lines, unhooked the kickdown. Bolted the trans pan back on and then placed the trans jack underneath the pan, and then leveled the trans jack, then slightly raising the jack upward for a tight snug. I placed the strap around the tranny and then crank down til tight. Removed the crossmember, removed the trans to engine bolts and the tranny backed out without a hitch! Lowered carefully, and then removed the dipstick at bottom, then rolled from underneath the truck.

Thanks to all for the helpful advise.

Will post soon after gettin transmission rebuilt!
