dancome433 Posted March 5, 2009 Share Posted March 5, 2009 ok so i couldnt figure out why my comanche wasnt starting, then after learning a thing or two here, i realized it was the CPS, went got me a new one and as I was taking out the old one when i figured out why it wasnt working, stupid me put it on backwards and used a different bolt that doesnt work for where its suppose to bolt in. So what i need to know is does anybody know what size bolts hold in the CPS to the bell housing? and also anybody have and good advice or tips to put it in, turning a wrench a sixteenth of a turn sucks Link to comment Share on other sites More sharing options...

jtdesigns Posted March 5, 2009 Share Posted March 5, 2009 To more easily remove & replace the CPS use a floor jack to support your transmission cross member, remove the two bolts & two studs (replace those with bolts if you break one), then lower the transmission cross member by about 1-2 inches. This will give you enough room to get your hands & tools in for the CPS work. (Especially if you have big hands!) Link to comment Share on other sites More sharing options...
Wildman Posted March 5, 2009 Share Posted March 5, 2009 But I've dropped the tranny down as far as I can......5-6" :D The bolts are a "shoulder" type bolt, I got some loose ones, and need to get to Fastenal to find out what size and stock # they are :hmm: Link to comment Share on other sites More sharing options...
moparmatt Posted March 5, 2009 Share Posted March 5, 2009 I get about 3-4 feet of extensions and one of them knuckles (Like a U-joint, universal joint) and go past the T/C and use a ratchet up there. This one requires a helper while breaking them loose you need someone to hold the extension near the bolt so it does not pop off the head. I have changed 3 of them that way. First one I changed took a couple of hours :fs1: (I have big hands), second and third too 40 minutes. That includes driving to advanced and back! I do NOT drop the tranny and t/c sounds like a lot of work. 8 less bolts I have to take out. :D Link to comment Share on other sites More sharing options...
dancome433 Posted March 5, 2009 Author Share Posted March 5, 2009 thanks everyone, I tried using extentions, but they kept popping off. and i have a torque gun, so i think i can get the cross member bolts out in a min or so, I'm going to try lowering the transmission just a tad bit Link to comment Share on other sites More sharing options...
Eagle Posted March 5, 2009 Share Posted March 5, 2009 The CPS bolts have a shoulder that's sized to locate the CPS properly. Buy it from a dealer. Link to comment Share on other sites More sharing options...
Red 1989 MJ Posted March 5, 2009 Share Posted March 5, 2009 Been there done that. Lower the trans. with a jack With a ratchet and a couple of extension you can unscrew the CPS with a TORX socket. Buy mine new from Dealership. Link to comment Share on other sites More sharing options...

500 MJ Posted March 5, 2009 Share Posted March 5, 2009 Yep - they are special bolts. I've never seen them in ANY hardware store. :( Link to comment Share on other sites More sharing options...

If you don't, you may get lucky and get it in the right position, but it's not likely. Even if you do, it probably won't stay and you will be stuck with a non-running truck again. Don't risk it...do it right and you will be thankful. :cheers: The Chrysler part number is 6503520 That should be a bolt & washer combo...and, obviously, you need two. :thumbsup: Link to comment Share on other sites More sharing options...
Rockyrider367 Posted March 6, 2009 Share Posted March 6, 2009 Is the special bolt situation the same between the 4.0 and the 2.5? I just put mine in with a standard bolt and works fine? Should i replace this? Link to comment Share on other sites More sharing options...

ren Posted March 7, 2009 Share Posted March 7, 2009 The 2.5 and the 4.0 use the same CPS bolts. I usally get them from the junkyard for nothing, along with other hardware that nobody ever seems to want, until they can't find theirs. I tend to collect these bolts and throttlebody bolts, bumper bolts and other such like the IRS collects back taxes. :D Link to comment Share on other sites More sharing options...
