Loose shifter, type A tranny

[sahunt66]

I used the search function and didn't find a clear answer to my question...

I called MSA and told them that I have a '70 240Z with the original 4-speed and that it's loose where the pin goes through the fork. The sold me a new pin & snap ring, which I installed. It didn't make any difference. Is there suppose to be nylon bushings, washers, or something else there besides just the pin & snap ring?

Thanks,

Steve

Steve: The auction is for only 2 of the 3 bushings. It is missing the one for the end of the shifter.

BTW, these are for the "B" type trans. (which is sounds like someone has installecd in your 1970 vintage car). The "A" type trans had a shifter that used two big rubber bushings and the shifter mounted external to the transmission case. These "A" type transmissions were used from 1969 production until the beginning of 1972 model production (around 8/71 mfg date) on HLS30-U cars

Carl, I guess my '71 240Z will have a type A tranny correct?

You'll have an 'A' box unless a PO swithced it out.

Thanks. I am sure it is the original tranny. It didn't seem to shift as easily as my son's '78 5 speed. Of course I've only driven it once. Probably do a fluid change when I get it home.

Yep, your car would have had an "A" trans originally.

Carl am correct in saying that a '71 240Z VIN HLS30-22975 would be considered a series II?

I believe so. The info that I have indicates that what we call the Series II HLS30-U began at (or around) VIN HLS30-21001

I used to own HLS30-23313 and it was a "Series II"

Cool. Thanks. This car has the vertical rear defrost lines & fuel door latch.

The "A" style transmissions used in the Series I 240's are inherently sloppy with age due to poor design. That is one reasons they upgraded to the "B" style which uses the nylon bushings shown in the "sblake01" response. I found that the problem is caused by wear of the fork, not the pin which is held in place by that tiny snapring. I also replaced the rubber bushings holding the shift lever but it did nothing to reduce sloppyness. I decided to live with it!

For the B type transmissions that I've worked on, the nylon bushings (the ones in the eBay auction) have tended to get chewed up after 5 - 7 years and they fall apart. At that point, the connection between the shifter and the mounting pin is terribly sloppy due to the missing bushings. Put in new bushngs and everything is nice and tight again.

The "A" type tranmission that I used to have, the rubber shifter bushings would deteriorate and become soft causing the normal "monkey motion" shifter to become even more sloppy.
