Transmissions

[Rory McNeil]

Keep in mind that G Force offers several different transmissions, both in clutch assist and clutchless versions. After 20 years of running Jerico DR4s, I reluctantly switched over to a G Force G101A clutch assist 4 speed last year, after Jerico stopped making many new parts for the DR4. Supposedly they reversed this decision shortly after I sold both my old Jericos, and started offering replacement parts for the DR4s again. Having used both transmissions, I feel that each of these transmissions have positive and negative points, heres my take; Jerico Dr4 is lighter, and more "universal" , fitment wise. The Jerico came with 4 different trans mount configurations, and has 2 rows of shifter mounting holes on the tailhousing, about 1" between holes. So you can typically use a factory style trans mount, whether you have a Ford, GM or MoPar . Both my Jericos were top and bottom cover cases , which makes for easier sevicing and repair. By comparison, my G101A GForce has one trans mount (GM style), and one shifter mount position. So if the shifter is not where you would like it, you need to order a different mounting plate to put the shifter where you want it. The 101A main case is taller, on my car, the top of the case almost touched the trans tunnel. Being a side cover trans makes the G Force transmission not as easy to work on, as does the "handcuff" which helps to prevent the mainshaft from spreading away from the cluster. I found both GForce and Jerico good to deal with for buying parts, at least until Jerico decided to discontinue offering replacement parts, which I understand they have reversed. Oddly, Jerico required prepayment for parts, (no credit card acceptance), no such issues with G Force. I believe that with the DR4 and G101A, that the GForce has more strength, although I found my DR4s pretty durable at my performance levels (low 10, high 9 second 1/4 mile). Much faster and I would think the G101A would be preferable. Both transmissions shifted well, although I do prefer the Long Pistol Grip shifter on my G Force over the older Vertical Gate I used with the Jericos.
