I'm having some issues with the 4HP22EH auto transmission in my '86 635.
I'd like to understand my options for sourcing a replacement should I need to go down that path. Will any 4HP22EH transmission from a later E24 or from an E28, E34 or E32 fit the E24 without any mods? Or were there variances between vehicle models and/or years of manufacture?

Are all BMW ZF 4HP22EH autos the same?
