I am posting this in hopes of helping my friend.Who has a older bronco with a 351 Windsor.His issue is with a 4 speed automatic.That he has a Mr shift improverAOD kit.And the instructions are confusing!Not to mention all the parts for what has to be installed correctly.IF anyone has any real knowledge on this subject.Please let me know.And I will get the details for his problem to you.When at this time it comes down to three different areas.That each have afew different parts to be installed and all have springs.He tells me the parts that came with this kit do not match the install diagram.When in fact they need to.So he has tried various methods of installing the parts.With zero luck and its been months now.He tells me the place he bought the kit at.Knows nothing about install work. Thankyou
