To me, that sounds like rear end noise. Hard to tell though. I've had rear ends howl, but never a transmission (not to say it doesn't happen, just my experience).

I agree, it's probably the rearend... If the whine changes pitch when accelerating vs coasting, that's a 99% it's the rear. The 7.5" rears are famous for their whining...

A transmission noise would likely be continuous without much change, or possibly change pitch when the transmission shifts...

I'm not sure what exactly you want. In the first video in the beginning I start from stop and accelerating to cca 70 km/h. The same in third video (to cca 100 km/h).


What I meant was, to test if your 1 and 2 shift selections work, take off in 1, and see if it stays in 1st gear (should), then move to 2, it should stay in 2nd, etc.

I gathered that you were saying if you pull it into 2nd while you are moving and it didn't downshift, then there must be something wrong. I was just saying that it's not supposed to. Only if you are going slow will a manual downshift work. It will also work the way I said, upshifting from a stop.

Oh, so 2 and 1 means direct shifting? When I shifted from D to 2 it downshifted I think, because it jerked a bit (it isn't visible on the video because my camera was sitting in seat next to my leg) and RPMs jumped to more than 2000 by "45" MPH and before were bellow 2000 by "55" MPH - look at the second video before and after shifting.

The trans appears to be shifting fine.  All I hear is what sounds, to me, like a rear gear howl.

The tranny does sound okay.  Pop off the drums and have a look at the axle shaft bearings.  This may sound familiar to the rearend problems I've been having.  :dunno:  I used a set of those extender bearings and the sound vanished.

If the bearings are okay, I'd pop the pod open and have a look.

Hi guys, I'm solving problem with wrong measuring speedometer. You were speeking about speedogears. What type exactly I need? I've found some connection with rear brakes, so I have 9" drum brakes on rear.
Thanks, Trinom.

Without knowing the number of teeth on the transmission output shaft, it's a guess at best for what driven gear you need...

Basically you need to pull the present gear and count the teeth... IF your speedo reads fast, you need a gear with more teeth... Per a speedo shop owner I talked with some time ago, each tooth added to the driven gear will slow the reading approx 3mph...

There are online calculators, still they won't be accurate without correct info...

But I still don't know numer of drive gear teeth. Rear end Ratio is 3,45 and tire hight is 25,6". If It's 7, I need 19 teeth speedogear, if 6, it's 16 and if 8 it's 21. I think it is 7, because of the number of teeth is "in the middle" and allows you to use another tire sizes.
