my 01 convertable was downshifting hard. I replaced the solinoid pack but no luck. The bolts that held it in place were really loose and it was leaking. I took it to a local shop they pulled the codes. It had air in the system. seems that this type of trans will not bleed all the air once it is introduced. He fixed it for 100 bucks. I am posting this becouse of the number of posts related to hard shifts. this is a good trans but it takes alot of equipment to diagnose the problems with it. the tech also told me that the clearances in the clutch packs were good. seems that crysler trans will let the tech know when it is worn out. good trans it just precision made. it does not tollerate much in the way of poor or incorect fluid or lack of matainence
