Transmission Sound

[scott_74]

Hi all,

I have a 1974 1275 Midget. Last fall, it was a time for a new transmission (it was grinding into most gears), so I ended up replaced it with a newly rebuilt transmission. The clutch had been replaced two years prior, but I replaced the ring gear and release bearing this time around as well.

Afterwards, once the temp would get to normal, I experienced a noise while depressing/releasing the clutch pedal. My mechanic (who aided me with the swap) took a ride in it and concluded the problem to be in the transmission. I also experienced difficulty shifting into second gear at times. Long story short, I ended up replacing the transmission with another rebuilt one.

I no longer experience the noise, and I can shift into all gears smoothly, but I now get a NEW noise just in second gear. The noise is most apparent when shifting into and out of second gear, but I can often recreate the noise by pulling back hard on the shifter into second. The noise occurs regardless if the clutch is in or out. The noise doesn't occur at idle.

It might be important to note that both of the newly rebuilt transmissions weren't supplied with a reverse light switch (of which my car needs), so I was forced to use the neck of my original transmission in both cases.

Also of note, I just finished replacing the clutch master cylinder, rebuilding the slave cylinder, and redoing the clutch lines.

This is a link to a video I shot quickly this morning since it can be quite difficult to explain sounds using words. In both instances, I happen to be downshifting (and elongating the circumstance the second time).


Any insight on the matter is greatly appreciated!

Thanks.
Scott

No takers?

I was thinking of trying to mix in some Slick 50 with the gear oil. I doubt it'd help but figure it's worth a shot. Anybody have any experience with the stuff?

I figure I'll end up having to pull it again...but I really have no idea what to look for.

Thanks!

I like Lucas oil treatments. Never ate 50 before.

Sorry, can't help. Sounds terrible though, is it really as bad as it sounds? I've heard good things about Lucas Transmission Fix but with a noise like that, I doubt snake oil will do any good but I'd sure try it before I pulled the engine. If you try Lucas or something, heat it up first and use a pump, it's so thick it's hard to get into the gear box. I have a bit of a glitchy box too but I'm going to live with it as long as possible.

I used Lucas - and am pleased with the results, Transmission wasn't loud but third was a little grindy - much better now, and, yes it was a bear to get in

Thanks for the replies.

I tried the Lucas stuff but it didn't help. I think I'll be taking it out again to give it another looksee.
