tranny shudder

[93cutty]

Ok 93 cutty is at 200k mark and I noticed that sometimes when I shifted the car would not go into gear for a few moments so I changed the filter and fluid and that seemed to fix the problem but a few days later I noticed that when I took off in drive the car would shudder and slip unless I accelerated slowly or manually shifted. I unplugged the TCC and the car runs fine except now I don't have OD. Can any of you tell me what part number the TCC is I have looked around and there are several different types.
