1971 240Z Tranny swap, auto->manual QUESTIONS!

[batcave]

Thanks for the clarification. Hopefully there isn't too much difference between the '71 and 73' transmissions.

Oh, and be careful with those motor mounts! How on earth did you break those?!?!?

Ok, this may sound like a silly question, but here goes. I was given a L28 out of a 77 280Z the P.O. was going to crush. The price was right, free. I didn't realize it was had an automatic until I saw it waiting for me. After figuring out how to hoist it out of my pickup, I removed the tranny. That was the easy part, but the torque converter is still attached. I have a five speed in my 240, so I am all ready to swap over, but how do I get the torque converter off. Does it just pry off, I can't see anything fastening it on. Any help would be appeciated. I'd like to get the L28 on an engine stand and down from hanging from the ceiling.

I figured it out, pretty easy to do if you use a little common sense. Next time I'll look it up in the Haynes manual, instead of just eyeballing it. Gary

Hey gary how did you get the torque converter off.

[getrdone]

I'm in the process of doing the same thing. I think there were 4 bolts holding the torque converter on. Remove bottom shroud and they are pretty easy to get at. Chuck

If you're going to do a transmission swap, and don't car for originality. Don't bother with the 4-speed, get a 5 speed.....

Ben, nice color on that z. I'm hoping to finsh my swap in the next few days. I'm swaping an auto to a 5spd out of a 78. The rear gears are the same so overdrive on the 5spd should be nice.

getrdone, did you need to get the flywheel out of the manual 78 280z or did you just use the same one, I want to do a swap on my 78 280 but am not sure about the flywheel. Also how did your automatic do when you were driving on the freeway did it sound like it needed to change gears when you are going about 65 mph, like it needed an extra gear.

Hey 78 240zcar, getrdone is right, except I recall 5 bolts, I could be wrong. Turn the torque converter until the first bolt in back is at the bottom of the engine, remove, turn converter some more for second bolt and so on. Pretty simple.

Anyone in need of a nice looking automatic tranny is welcome to it (whether it works or not, I have no idea). I'd advise pick up in Oroville, Washington, becuase shipping might be high. I lifted it into a wheelbarrow, but should have used the chain hoist as my 43 year-old knees don't like to bend much any more. However, I wasn't ready to disconnect the L28 hanging from the garage ceiling. I already have the 5 speed on my L24, so I'm really doing an engine swap. Gary
