Hey guys, just doing a little research here. I am putting a Geo Tracker engine and automatic transmission in my Samurai. While researching this, I learned that the Isuzu 4L30E is based off of the Trackers 3L30 transmission. So I am thinking that I can use a 2.8 Isuzu engine and mate it to the Tracker transmission using an Isuzu bellhousing. How is this engine? Is it the same as a Chevy 2.8? Any other engines use the 4L30E transmission? Also, this may interest you guys. I am not sure what you guys have for options for T-case gears, but the transmissions also appear to share the same tail housing. If this is so, there is an adapter to mount a Toyota T-case to a Tracker transmission that could be used on this transmission. There is also an adapter to install a Toyota T-case to a Tracker T-case (which you could bolt to a Isuzu transmission) giving you a dual T-case set-up. Just something to think about.
