T5258:
I agree....my Spirit has a lockup converter & rpms drop by 2-300 when the converter locks (appox 37 mph)
philotomy:
Ok this may sounds stupid but...what does "lock up" refer to?I've been reading about it in Chiltons but I think I'm even more confused now.Mine is an 87 with non lock up But what would make them change it?
Mine's making a whining ,clicking sound,Is it gonna grenade on me?Maybe just a loose torque conv. bolt?cracked flexplate? :'(
IowaEagle:
A lock up converter, in simple terms, sidelines the fluid coupling between the engine and transmission to make it direct drive set up.

Whining noises are many times simply a matter of adding fluid. Clicking noises may indeed be coming from a loose/cracked torque converter/flex plate. Have you noticed any differences in how the car drives since the noises developed? For instance, a car that suddenly becomes noticeably sluggish getting moving from a standing start may have suffered an internal torque converter or overrunning clutch failure.

@IE:
Part numbers you mentioned can be found in the Eaglepedia parts list 1984 -1988 too. Doesn't show the years to them, but they must be correct.
Are you saying that no lockup was used after 1984?
I found a 1980 datasheet:
http://homepage.mac.com/christopher.z/hobby/80-DataBook/B15.JPG
that is telling me that only 6-cyl engines with 2WD have lockup.
In the 1982 TSM, you will find that 4-cyl cars have no lockup and 6-cyl cars have lockup
In the 1983 TSM supplement you will find that fleet cars have no lockup, others have lockup.
Don't read Chiltons (I did, pag.1-18): eg. 1985 - 1988 all models use lockup converter.
I'm completely lost :-\
Can you feel the lockup engage on an Eagle? If you can, mine doesn't have lockup.
