Are there any common problems with these trannies? I know they are not as strong as the Muncie/Getrac Trannies. This tranny has 247550KM on it, it has all 6 gears, and the clutch feels good (no grabbing or slipping). Is the clutch the same size as the 84 4.10 tranny? How hard is it to rebuild one? I have never driven a manual tranny car before, but I have driven a motorbike.

When you slow down, do you keep the clutch pushed in, or engine brake? Also, do you just down shift to 2Nd and then go into 1st when you stop, because 1st gear is pretty slow. One last question, 1st gear seems to be the hardest to down shift into when decelerating, is that normal, or is it just because I was still going too fast?

Thanks for answering my questions.

I'm not sure if the clutch is the same. Engine braking is fine if you do it correctly. Personally, I'm a double clutch kind of guy I wouldn't hold the clutch in at stops. This causes premature wear to the throw out bearing. 1st is typically pretty tough to get into at speed. The synchros take a bit longer to engage due to the speed you're asking the layshaft to make up. I don't shift down to 1st in normal driving. I usually drop it into neutral after second is wound down.

That is what I was thinking, because it is such a slow gear. Now that it idles and runs good, I can drive it pretty easy. I find it easy to shift when accelerating, so I guess that is a good sign.

I usually don't engine brake, because brakes are cheap compared to anything engine or transmission related.

Don't shift to first until already stopped. This is for any manual transmission.

Coasting saves gas, so you can burn it when the light changes.

I second that! Much easier to change the brakes than the clutch and it saves wear on the tranny.

Back in the old days with drum brakes down shifting was a must
to get any kind of speed reduction and brake longevity (at the track).
With the introduction of disk brakes by jaguar at Lemans in the 40's (?)
this become unnecesary. also , engine braking only loads the rear wheels
and combined with normal biased brakes still puts too much braking at the
rear(can you say off throttle oversteer boys and girls?)j/k


proper cornering technique with a modded street car (generally accepted)
is to get all of your brakeing done in a straight line, down to your
cornering speed, and choose the correct gear before the entrance to the
corner. Now you want to balence brakes and throttle, to not upset the fine
balenceing act at max g's through the corner.

Heel and toe or left footbraking are the technics used.

Lift on the brakes or the throttle and "good bye"

This allows a very late apex and still carry speed. Just past or at the apex
is the time to gentley dial in more throttle just enough to shoot out ot he
corner but not too much to cause any oversteer (this scrubs off speed)
Now you focus on clean shifts and prepare to do it all over again at the
next corner.
When you get it righ, corner after corner, the feeling is such a rush
do it consistantly lap after lap and you will lots of brakes and clutch left.

I have learned this at various performance driving schools at race tracks
in canada. I have also instructed at
The Porsche Advances drivers school
Audie Experience
and Mercedes Driving Excellance

this style is not the only way through a corner but it is one way that
will yeild consistant results

every car is differrent an so might need a variation to this technique
