So my 96 SE sounds like its shifting OK.
Its the SSE thats shifting late @ 62 -65 MPH.
Maybe that needs a TV cable adjust.
Last time I tried I couldn't get it to unclip unless there is a trick to it?

I've gotten TCC 3rd at 38, and TCC OD at 50. I think there is something up with my tranny. Hmm.. what a surprise.

My TCC locks up in OD as early as 40mph. I go into OD without TCC at the earliest 30mph.

Come to think of it my SSE started shifting later when I put the bigger tires on.
Must have effected the gear ratio.
30 is way too early for OD.
