I did the rebuild at a friends house, as they have a large garage. No

there ever heard of anyone ever taking a manual transmission apart,
replacing parts, and putting it back together and having it work without

any

issues and actually lasting.

Then again, I was ripping dirt bike engines and transmissions apart and
rebiulding them when I was a early teenager.

Now I just work on equipment like this:

But I bet all the car/bike repair experience helps with that as well.


Absolutely! Dad being a skilled automotive mechanic also helped.


Done it myself with a friend
after his car's reverse gear lost a tooth, back in college.


This was the same time frame for me.



We had to
hand-carry the whole gearbox across the German-Dutch border (!).


Not sure about the relivence of the German-Dutch border (I haven't been

out

of North America!), but the typical manual transmission being around

100 -

150 Lbs wouldn't be fun to carry for a long distance even between two
people.


It was a small Vauxhall or


Opel.


Didn't they have GM drive trains? Not sure, but I know some European /
Australian cars did. Then again I never heard of a tooth breaking in a GM
car here, especially reverse which are noisey, cheap straight cut gears, but
are generally very strong.


I really don't remember. It was a smaller version, I think called "Kadett" or something in Germany.


Their engines over there are rarely
above 1.6 liters so the transmissions are accordingly small. Could have
been 100lbs, don't remember. We were already beer-primed by then ;-)


100 Lbs would be likely - the larger ones just beef up the parts a little
more, adding say 50 Lbs.


While
at it we managed to deplete a crate of Grolsch beer pretty good.


There was beer involved when I did mine, I can't remember what type, but

it

was Canadian, maybe Labatt's or Olands


The problem was that we could not test drive the car after putting the
transmission in again, on account of the number of consumed brewskys.
Both of us would never drink and drive so we waited until the next day.


I would've had a similar situation but a friend did the test drive, and
delivered the car to my house.


Afterwards a couple parts were still on the table. Hmm... But: It worked
flawlessly and now down-shifting from 3 to 2 worked with ease. It never
did with that Opel/Vauxhall before. So we had improved and cost reduced
it but didn't remember how ;-)


! ;-)

Likely something to do with the syncro - was the leftover parts spacers

or

shims?


AFAIR it was spacers.


Almost guaranteed it was something to do with the syncro. Neat little
devices. Motorcycles generally don't have them, not even motocross bikes
which need very fast shifts. This is likely due to the much lower rotating
mass and the engine's RPM's are geared down a lot before they go to the
transmission. Most work like the reverse gear in most car transmissions,
which is not synchronized.



I never have unknown parts left over, as I visualize how everything

works,

and every part was put there for a reason. I always figure out why that

part

is there. Some have some surprising hidden uses. I've been known to take
boxes of parts from a motorcycle transmission and engine, without a

manual

or any other aid, or even seeing the unit assembled before and put it

back

together without issues. Figuring out the transmission in one of those

is

not exactly fun if someone previously took the gears off of the

shafts.To

add to the pain, they go together in several possibilities and often

have

extra features milled into them, so the same part can be used on

different

models thus confusing the matter.


Well, all I can say is that the car later went to the owner's brother
who was a trained and certified car mechanic. When he took it for a spin
and noticed the easy 3-2 downshift he asked "How on earth did you guys
do that?"


Interesting. So those transmissions have been known to have hard downshifts
into 2nd. I wonder if the transmission was just as durable? Perhaps someone
responsible for the assembly line misunderstood the shimming specs for the
sycro's and had them all built wrong!


These cars all had a harder 3-2 downshift back then, according to folks who owned them. Well, all but one of them ;-)
