Eagle Posted September 29, 2009 Share Posted September 29, 2009 I know the 2.8L V6 as used in the early XJs and MJs was externally balanced. On the manual transmissions, that meant a "bob" weight on the flywheel. On the automatics, is the eccentric weight on the flex plate, or on the torque converter? I *NEED* to get my '88 2.5L 4-speed on the road. Clutch is blown. I could replace the clutch, but my wife doesn't drive standard (and the vehicles appreciate the consideration!), and it would be nice if there were a truck she could use when she buys used furniture for one of her projects. I have an ad in the Classifieds looking for an automatic for a 2.5L, but it occurred to me that I have the hulk of a 2.8L out back with a transmission attached. I'd have to replace the 228 transfer case with a 231 or 207, but that's not impossible. I know the tranny will bolt up to the block, and I assume (perhaps foolishly) that the torque converter may work, but will a 2.5L flex plate take care of the eccentric weight issues or will I have to have the torque converter neutral balanced?

Pete M Posted September 29, 2009 Share Posted September 29, 2009 does the 2.8 bellhousing have a place for the CPS? Link to comment Share on other sites More sharing options...

dasbulliwagen Posted September 29, 2009 Share Posted September 29, 2009 If the same type trans was also used in the 2.5s, there may be a place in the belhousing, but just not drilled out or tapped. I need to look into this myself to as my 2.8 donor trucks AX5 is slated to go in my 2.5. I hope it will work, or else Ill be looking for a new belhousing.

86FUBAR Posted September 29, 2009 Share Posted September 29, 2009 does the 2.8 bellhousing have a place for the CPS? As a matter of fact the bellhousing on my 2.8 AX5 does have the hole for the cps and the bolt holes are threaded as well , its funny this is mentioned though as iv been in and out from under the hood of the manche so many times i never noticed ( at least as i can rember) that the hole is there and it is quite visible from the top side . needless to say the hole is geting a sheetmetal cover made to keep mud out.

Geonovast Posted September 29, 2009 Share Posted September 29, 2009 I don't see why they wouldn't have bothered not tapping them for the 2.8, I'm sure the transmissions were all completely built before it was even determined which motor they went behind.
