5th gear problem (not this again)

[ashah000]

Ok guys remember a while back that crazy guy that was taking about 5th gear popping out

Well i was driving today and it happen , just driving at 45 mph and it came out. Then I took it around the block to see if it will happen again but it didn't. So was it just a one time thing. Is it a loose nut down there... I just installed a short shifter.

what kind of short shifter and how much throw reduction? and what are you doing cruzing around at 45 in 5th?

I found this at www.vfaq.com....hopes it helps.

This is a symptom of a serious problem, at least on 1G DSMs. Shifter movement is not generally normal in DSMs. Having the shifter move around, especially in 5th gear, or popping out of gear (even once or twice) could be an indication of a loose retaining nut inside the transmission. Several 1G DSMers have had the rotten experience of having this nut come off completely, and consequently blasting a hole in their transmission. This problem only affects FIFTH gear - gears 1 through 4 and reverse do not appear to suffer from this difficulty.

Those who are uncertain must read this post and this post, both by Paul Lyons, and this one by Ashok Babu, who had his transmission fail on him. Don't take a chance on this one, since the inspection procedure is easy.

This problem does not appear as common on 2Gs, and at least one owner has reported that there was a loose nut in his shifting assembly that was causing the shifter to pop out of 5th. This is NOT the same nut that is involved in the 1G problem.

Is yours a 1g or 2g?

Homemade shifter... hehehe
Actually i like it. It was cut 2.5" less then stock.
And I can see the radio now. The throws are pretty short, but i dont know how to calculate the percent, otherwise i would- it would be interesting to see.

And the link does not work... but i will try to find it.
And my car is a 2g, hoping it is not anything serious.

ummm... why not

I can tell you the percentage decrease in shift length if you tell me how long the shifter was before you cut it (or is now).

Because 45 in 5th gear is way low RPM's and most people don't cruise that low.. you won't be able to accelerate at all.

Sweet...
Do you need the whole length from top to bottom. If so...
It was 7" and now its 4.5"

And yea it is low, apx. 2000 - 2100 rpm but when i am crusing i dont care about acceleration, I need gas mileage. I can always downshift if i need to accelerate.

35.7% less.
I remembered it being harder, but arc length of a throw is directly proportional to radius (shifter length) and angle which is a constant, so doesn't matter.

[ashah000]

So 2.5/7... that really does seem to easy.
I guess 35.7% is not bad, better than most short throws, except the 50% ones.
My throw is really short, I could only wonder how 50% would feel.

[BoostedSpyder]

actually i think it should be calculated from the fulcrum of the lever to the top. and it would be a little more of a complicated math problem. not that much, tho. and if you really think about it the angle of shift arc would be a constant because it is the same lever, but the length of the arc would be reduced. the length of the total piece would be reduced by 35.7%, but the lenght of the reduction in throw arc would be different. 100 - ({[new arc length]/[old arc length]} x 100) would give you the corrected percentage reduction. i think i just hurt my brain...

[ashah000]

Wait that is still 35.7%... im confused.
I'm going to ask my physics teacher tomorrow

[JoeWagon]

I thought 7 inches WAS from the base of the shifter, at the angle theta.

[ashah000]

Wait I think my stupid brain is playing tricks on me.
I measured this over a month ago and I can't remember if I measured the lever or the whole thing.

I am going to re-measure it right now.
Sorry guys.

[ashah000]

Ok it was messing with me--as usual

Here are the real measurements:
Current length from top to bottom 8.5"
Was cut: 2.5"
So i calulated 22.72%

However is the fulcrum at the bottom. There is a hole in the shifter that it goes through. Would that not be the fulcrum? But then again it is connected at the bottom too.

[JoeWagon]

Meh, whatever.. its pretty accurate

STOP IT my brain hurts just reading this lol
