Transmission Swap Complete!

[glassguy]

Well, my auto to 5 speed manual transmission swap in my 7/71 240Z is complete! I couldn't have done it without all the help and advice from the numerous members of this site! The main issue I had was that the transmission I bought from a junk yard that was out of a 78 280Z had a throwout bearing collar that was for a 4 speed transmission. Of course I didn't realize that until I installed it and found out the hard way. But now I know which collar goes with which clutch set. I do have to say that the automatic transmission was much quieter than the 5 speed. But after researching numerous threads on the subject of noisy manual transmissions in old Z cars,  I've decided not to let the little bit of extra noise bother me too much. Besides, I'm too busy having a blast shifting through the gears and going faster now! My only concern so far is that it will pop out of 5th gear sometimes, and during an agressive shift into 3rd gear there might be a little grinding sometimes, but not so bad that I'm gonna pull out the tranny for the 3rd time. I think for now I'll just drive it awhile and see how things go before I jump to conclusions. I have read in a few threads that these Z's don't like to sit, so I'll just drive it and see if it gets better for now.

Try using motul tranny fluid.

For popping out of 5th gear you can pull the spring (with ball) out of the main plate in the gearbox.. it is sitting behind a bolt.. take a new spring or make it a bit longer with help of a side cutting pliers..(just give it a pinch between the windings, not cutting ofcourse..)  just a few mm longer will do!
