Oly Posted April 29, 2013 Share Posted April 29, 2013 I need help please someone. i made a rookie mistake because well....I'm a rookie. so i have an 88 comanche that is going to hopefully have a 6 cyl 4.0 and auto trans that I'm removing from a 91 cherokee donor. from what i can tell should be a direct bolt up. my issue is i pulled motor and trans and un bolted trans from engine. i unbolted the torque converter first however I'm a dumbass and didnt mark the torque converter to the flex plate now i don't know the way i should re-bolt it up for it to work right with the crank positioning sensor i believe. sorry for the inconvenience and thank you for replies. ~Oly~ Link to comment Share on other sites More sharing options...
jimoshel Posted April 29, 2013 Share Posted April 29, 2013 CPS works off the flexplate. torque converter, or it's position has nothing to do with it. Link to comment Share on other sites More sharing options...
Oly Posted April 29, 2013 Author Share Posted April 29, 2013 awesome there is some relief. now this may be a dumb question but i have a haynes manual and it says to mark to torque converter to the flex plate. why is that for balance purposes?

87manche1 Posted April 29, 2013 Share Posted April 29, 2013 There's multiple holes its obviously going to be the ones with a spot of no rust where it bolts to Link to comment Share on other sites More sharing options...
Oly Posted April 29, 2013 Author Share Posted April 29, 2013 right well i gathered that much. so it doesnt matter which hole lines up with which hole as long as the original holes were used and all four bolts are securing the torque converter? it just seems wierd to me why it would say it has to be marked and i must match up how i marked it. and is there only one way to put the flex plate back on as far as it lining up properly?

cruiser54 Posted April 29, 2013 Share Posted April 29, 2013 Are you sticking with the Renix system or converting to the Chrysler system? Flex plates are different. Link to comment Share on other sites More sharing options...
Oly Posted April 29, 2013 Author Share Posted April 29, 2013 the motor and transmission are both stock in the cherokee. 91 so i believe its chrysler right? i just seperated the motor and transmission today I'm not changing anything so i know they work together. sorry if I'm not providing much info like i said I'm a rookie Link to comment Share on other sites More sharing options...

Geonovast Posted April 29, 2013 Share Posted April 29, 2013 If you're just swapping the motor and trans, you must use the 88's flexplate. I believe it can be easily redrilled for the HO's converter. If you're doing all the wiring and control system, then leave the 91's flexplate in. Do you currently have a 6 cylinder, or do you have a 4?

cruiser54 Posted April 29, 2013 Share Posted April 29, 2013 Doesn't even need redrilling. Swaps right over. OP- We're trying to keep you from making a huge mistake!! Link to comment Share on other sites More sharing options...
Oly Posted April 30, 2013 Author Share Posted April 30, 2013 hey guys thank you much for the replies. currently i have the 2.5 4cyl in it. i am swapping the motor trans wiring and pcm radiator all the other fun $#!& that goes with it. however i am rebuilding the 6 cyl b4 i put it in. so unfortunately i already removed the flywheel from the crank and again i didnt mark it like a jackass. so how do i insure i get the flex plate/flywheel in the right position? and also does anyone know the size bolts i need and thread to mount the motor on a stand? thank you again everyone!

cruiser54 Posted April 30, 2013 Share Posted April 30, 2013 Okay. Now we have the whole stroy. The flexplate only goes on one way................ Link to comment Share on other sites More sharing options...
Oly Posted April 30, 2013 Author Share Posted April 30, 2013 lol sorry bout the lack of info. why did u say as long as the flywheel stays on the crank i will be ok then? also one more question....my 88 comanche with the 4 cyl 4 speed does not have a check engine light at all. i have even removed the cluster and "info center" dash thingy and there is literally no check engine light. its throttle body injected so i imagine i would have some sort of engine check light or something right???

Geonovast Posted April 30, 2013 Share Posted April 30, 2013 Lack of a CEL is irrelevant, as you're going to be using the 91's cluster. Link to comment Share on other sites More sharing options...
