Hey all,

I've been a member here for some time and used to have a different name (Watt), but somehow my login stopped working and so I've been lurking from this new moniker for awhile...

I've got a 69' Nova and am pulling the engine (400 SBC) and trans (TH350) this weekend and have everything for the engine stripped, bagged, tagged, wires labeled etc. Now I'm onto the transmission and I've been looking around through google and SNS but can't find a step by step on what needs to be done to get the transmission ready to be pulled with the engine.

If anybody has some information would they mind helping me out?

Thank you in advance!

I think that for most backyard builds, pulling the motor and transmission together is going to be easier. If you try to pull them separately, you usually have to get the car up on stands high enough to get the transmission out from under the car.

The aim here is to disconnect everything and yank them.

1. 4 bolts on ujoints to remove driveshaft. Wrap the ujoint caps with tape.
2. Trans mount / crossmember removal.
3. All electrical disconnected and labeled. Usually this is like starter, ignition system.
4. remove speedometer cable
5. remove trans cooling lines
6. remove upper and lower radiator lines
7. remove all mechanical and electrical gauges lines (i.e. temperature, tach, etc) label as needed
8. remove shift linkage
9. once it appears that the motor and transmission are free of all obstructions, yank it after pulling the motor mount bolts.
Excellent. Thank you! I'm going to get this prepped today and wait till I can get a couple friends over this week to help me get them both out safely.

I just went through this 6 months ago alone. My 2 cents... An engine leveler is a must with lift chains bolted to the front and back of the heads, $50 from HF I think. Get a $10 plastic trans plug to prevent leaks. Pulling trans and motor is a breeze with those. Definitely pull the radiator, the fins bend to easily if you bump it so spend the 10 minutes removing it. Once the engine is high enough and trans is level to clear the core support then roll the car out of the way. Wait till the above is complete, then drink beer...
Thanks for the info Dan. I borrowed a friends hoist with his chain leveler so glad I'm headed in the right direction there. Ordered the trans plug earlier this morning like snolan mentioned as well. Will definitely remove the rad for the extra inches.

I was trying to undo the cooler lines going into the trans but the extension pipe that comes right after the header was in the way. So I thought I’ll just undo the headers now and hope that gives me enough room. Got all the bolts out until the last one that’s close to the firewall. I can’t get a socket on it because the header is in the way (header is dented in for the bolt), and I can’t get a wrench on it from top or bottom either because it’s a tight space. Any suggestions on a tool or a trick that might help me?

Crows foot could work for sure. May try and add some heat to the header first and dimple it in a bit more. I’ve got a torch I can borrow and that’ll save me a trip to princess auto or Canadian tire.

Jeez Louise! That’s great! I’m almost done prepping but will definitely use this to reassemble or next time I need to pull an engine. Thanks a million.
