I also had to notch my tran tunnel crossmember to make room for the straight shifter rods for the V-gate. I posted about my Jerico installation in my Mach 1, so that may show you a couple of the changes you might have to make (link here if you want to check it out. I love shifting at the track with the Vertigate, but I can't compare it to the pistol grip because I've never used one.Įither way you go, you will have to cut a bigger hole for the shifter. I think the pistol grip would be easier to downshift because you don't have to reach over the shifter to pull up on the gate lever, but mine works for me. It's not the smoothest downshift, but it goes into gear solidly if you rev match. My Jerico has the clutch assisted sliders (not road race) and Vertigate shifter, and I can downshift on the street. I wanted something that could retain all the parts I had (Mark Williams driveshaft and stock crossmember). Same here on going with the Jerico over the G-Force. I am very happy with the G Force, but if the parts problem never happened, I would have kept the Jericos. I do like the fact that the G 101A has a "handcuff" to help keep the main and cluster shafts from spreading apart, especially in 3rd gear. The G Force is a bit heavier than the Jerico, as well as having a slightly taller main case. Both my Jericos and the G Force had similar gear ratios, so performance didn`t change, the G Force seems easier to shift, but that may be due to my G Force has the later "Pistol Grip" shifter, where both the Jericos had the older style Verti Gate shifters. So to locate the shifter where I wanted it, I had to order a different shifter mounting plate and rods from Long shifters, which is part of G Force. Also, unlike the Jerico, the G101A has just the GM trans mount pattern and position, so I had to modify my trans crossmember, as well, unlike the Jerico, which had multiple shifter bolt holes to move the shifter position, the G101A has a single MoPar style shifter mounting provision. Naturally, shortly after selling both Jericos, they changed their mind, and started making DR4 parts again! I did have to make a few changes to the car when I installed the G101A, like Dale said, I needed a new driveshaft, as the GForce was about 2 inches shorter than the Jerico (same 32 spline output spline though). I was lucky that a buddy had an extra mainshaft, but Jericos decision to turn their back on all the racers who were using their products, I figured I would buy a G Force G101A, rather than reward Jerico by buying a DR4-4. I broke a mainshaft in the Fairmonts Jerico, and when I called Jerico to order a new one, thats when they said they were no longer going to make any parts for them. An air shifter can be specified as optional for drag racing applications as well.I ran the older style Jerico DR4s in my Fairmont and 85 Mustang for 20 years, and I would still have the same Jericos, had Jerico made the wise (?) decision to deem the DR4 "obsolete", and chose to not supply replacement parts for them. Like G-Force models, this transmission comes with your choice of a Long H-Pattern or a Vertical Gate shifter. The GF-5R is a versatile transmission having a wide range of applications: drag racing (both clutchless and clutch assisted), road racing, off road, and street/strip vehicles. The GF-5R gets an increase of 15% more torque by using 4 speed gears in this 5 speed. This transmission features more internal bearing supports than any other racing transmission on the market today.Ī new 4-speed tranny, the GF-101A, for Stock & Super Stock Classes, will be available in either Clutch Assist or Clutchless models $2,500 for reconditioned models and $4,500 new. It has now been made available to the general racing public to prove that G-Force is committed to bringing the best possible products to the racer. This clutchless 5-speed developed specifically for professional Pro Stock teams has endured countless hours of research and development and an equally rigorous testing agenda. The top of the line GF-2000 is getting an increase to handle up to 25% more HP. Michael Long of G-Force was introducing some new bits and pieces at the PRI show. The company’s products are engineered using the most up-to-date CNC machining technology and computerized inspection equipment to optimize accuracy and repeatability. G-Force has been producing high performance transmissions used by many of today’s top NHRA racers for more than 14 years.
