Hello. I am a new member to this site. I am seeking wisdom an guidance not criticism an slander. I am the proud owner of a 1990 jeep Comanche. It is 4x4 an has an 6.5in lift.. I happily put just at 327k miles of thrils adventures. U name it places I went there... But that was before the crank shaft seised in place. Resently I acquired a 2000 jeep Cherokee with 125k miles for $600 with a title... It's a 2wd however... An that it had been rolled. When i bought the cherokee the guy couldn't get it to start after it had sat for a while. I having been a jeep tour mechanic the past 6 years in Sedona az I knew... So I put a fuel pump in it and a brand new battery.. an it started right up.. And i would just sell it an buy an year correct new replacememt 4.7 stroker for an renix bit the cherokees been rolled and its a awd.. So ive already pulled my comanche motor.. Here's my project an my delima. I have the renix 4.0 removed .. I have started isolating the wireing harnesses as well as started removing the interior dash boards in both vechicles. I need help with this. The Cherokee is a 2wd I want to retain my asain warner 4 speed 4x4 trans in my comanche an transfer case if at all possible. As its fairly new only has 60k miles on it.. The 4.0 ho I'm pretty sure has a aw4 as well from taking multiple pictures of the 2 transmissions an comparing them there identical just updated sensors different wireing. An ones onle 2wd... In my Comanche i started removing the dash trying to remove everything from engine bay. except for steering an brakes.. An what ever transmission wireing an tcu.. So the question is. Is it possible to retain my 1990 trans??? just swap the entire 2000 in to the Comanche right? Dash all engine bay wireing lights... I want to swap Cherokee dash an I have too but I want to keep my steering column shift so I need to keep the wireing for the multi function switch the ingnition switch horn... Hi do I get around that wireing issue with the obd2 demand for computer communication with ever electron gismo an doo hicky in the vechicle... Also another thing I wanna cheat are keeping my wireing going to rear taillights. Call me lazy but i really don't see the point in running all new wireing back there.. I already need to wire up a trailer hook up as it is. Getting off topic. So i Can't get my head around how to adapt my trans harness an or what to leave behind in Comanche inside an out coullm shift wireing.. b4 I start pulling Cherokee motor am get that ready to go.. I wanted to strip my Comanche completely clean nothing there but the abasloutly essentials an lay in all Cherokee wireing an dash board first. Then I wanna install the 4.0HO after I put a new rear main in am intake gasket am timing cover gasket new water pump everything new while I can with engine out.. I've been eye balling my old busted gear box leaking all over the one in the Cherokee looks the same I think I'm going to swap that out an I was looking at the brake booster in the Cherokee that looks masive compared to the 90s booster maybe even update the calipes I don't see the need.. Would like to convert to rear disk.. Off topic again... So. I Need to move on past this transmission wireing an steering collumn shifter wireimg... holding me up.. I've read some forms on renix to 4.0HO swap.. Here's a breif summary an the end result of what route I chose to do.if Posted 21 January 2011 - 07:34 PM Renix to HO swap: Method #1: swap in the HO engine/head, keep the Renix intake/exhaust/TB, etc (have to somehow match intake to head) Method #2: swap in the HO engine/head/manifolds/TB, but keep the Renix control & sensors Method #3: swap in the HO engine/head/manifolds & HO engine control system in. So I went with option 3... But I have a transmission problem. Or do I? Couldn't find anything about this issue.. Trying to keep a 90's trans with a 2000 engine... Can it be done?. I'm pretty sure it can! I have wire loom almost completely bremoved on all engine bay harness in Comanche I can provide pictures upon request... Any an all help. Greatly appreciated... Thank you!
