G-Force GF5R transmission assembly...Video 1 of 3
This is video 1 of 3 of me assembling my G-Force GF5R 5 speed clutch assisted transmission. I haven't seen much on these transmissions online other than pictures so I figured I would make a simple video of re-assembly the next time I had it apart. It was clutchless and I disassembled it to change it over to clutch assisted so I can drive it on the street. I had the camera mounted to the side of my head so the footage is a little bad at times. Like the Doug Nash 5 speeds these are very easy to work on if you have the proper retaining ring pliers. I have other videos on Youtube of my car with this transmission when it was clutchless. I also have videos of my car with a Jerico 4 speed and a Doug Nash street 5 speed. The car is a 1979 Monte Carlo with a naturally aspirated 408 SBC and runs mid to low 10's.

1987 SCCA Bendix Trans-Am Race Sears Point, Sonoma, CA 1 of 5
1 of 5 Some great racing at Sears Point in the 1987 SCCA Bendix Trans Am - including some really cool in-car video of the Roush Merkur XR4Ti beasts, in their 4cylinder turbo trim during this race (later converted to V8 -- note I raced against these cars up in Portland at last years historics race, you can see some in-car of that on my channel as well) -- There are also some interviews with a very young Scott Pruett here too (Formula-1 Scott? :) ).





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 dragstrip.
