In-Car Shot Dragracing Lenco Transmission Video
This is an in-car shot of Mike drag racing his 73 Duster using a Lenco
transmission. His dial in time is 10.60 and his ET for this race was a
10.61. This video shows the fast accelleration of a Mopar motor.

Big Block 4 Speed Chevelle Drag Racing Video
**BEST 11.61 @ 121mph, 1.69 60ft all at 3800lbs!!! Had the mph for a bottom
eleven and still didnt have all the bugs worked out. Didnt get to turn the
wick up to much, only ended up shifting at 7200, though the motor makes
peak power at 7600, so there is much more left in it. NEW COMBO : all new

Jerico DR4 on the street...Video 1
This is my 600 horsepower mid 10 second
Monte Carlo on the street with a non syncronized Jerico DR4 4 speed
transmission. No clutch used for the 2nd, 3rd, or 4th gear shifts. The
video also shows a downshift from 4th to 3rd with no clutch(done as the
final car passes me and before I get on it). The upshifts and downshifts
are all done by matching rpms without the use of the clutch. For upshifts
as you let off the gas just pull into neutral and let the rpms drop about
800-1000...then put in next gear. For downshifts say from 4th to 3rd just
push into nuetral as you let off gas, raise 800-1000rpms and push into
3rd. I just wanted to put this video out there for people wondering how a
Jerico works out on the street . It took me a long time to figure out the
best way to drive the Jerico on the street and with some practice I now can
do it with little to no clash or noise. This is with careful driving and
slow shifting though. I have a couple other videos that show a bit faster shifting but still just tooling
around town. The only time I get some clanks is when I take a slow corner
and snatch it into second(I do use the clutch for this), and occasionally
when I put it into 1st at a light. Hope this helps some of you
street/strip manual trans guys thinking of going with a Jerico. And this
transmission does have the "road race" sliders in it, many people think
that means it is syncronized..it is not. The road race sliders have
squared off slider faceplate lugs and the drag race sliders have ramped
faceplate lugs. Being squared off means there is a nice flat surface on
the coast side of the slider faceplate lugs which is where the contact is
during a downshift. Unless you see pics of the inside of a Jerico this
will be hard to grasp. Basically if you are going to street drive you want
the road race slider...and it will still powershift perfectly at the
