It`s too bad that the people that bought Jerico chose to ignore so many of their loyal customers, and eventually ran the company into the ground. I had 2 Jerico DR4s that I ran from 199 thru 2018, and was very happy with the transmissions, and had no problem getting parts from Jerico when needed. But when I broke a mainshaft on the Jerico in my Fairmont, when I called them to order a new mainshaft, they told me that they were no longer going to supply parts for the earlier models, and suggested that I buy the latest DR4-4 version. Luckily a buddy had an extra mainshaft in his stash of parts, so I was able to finish the race season. But since I felt that Jerico had turned their backs on a loyal customer, and hundreds of others, rather than give them my money for a new transmission, I bought a barely used G Force G101A 4 speed. In 7 years of running the G Force, I have not done anything besides change the fluid, but at least it`s nice to know that if and when I do need replacement parts, they will be available. Sad what Jerico did, as it appears that the racers running Jerico DR4s greatly outnumbered the G101A drivers, but for whatever reason, Jerico chose to ignore their customer base. I am guessing that there are enough guys with Jerico parts laying around, that they will still be guys running DR4s for many years to come, and maybe somebody will try to revive the company or start making parts for them, but in the meantime, I am guessing that as DR4s break, many will be cannibalized for parts.
