wow i havent postest in almost a year
hopefully i havent missed too much.....
as for your TCC, this may not help but its a start, is your engine running at operating and running at normal temp? The TCC will not "lock" to a 100% coupling until the engine/transaxel is warmed up enough, around 120 degrees is about when mine will engage.
also ive found that when the shifter is in 3rd (D) and
cruise is set above 45ish mph the transmission will not go into TCC "lock". Only when in overdrive will it the TCC lock when cruise is on. This is for my 88, on my dads 93 the TCC will lock in both drive and overdrive while the cruise is set. the 93 transmission is newer "4T-60"
hope this helps, get back to us
