Might be - but Nah!

The 87 gets better.

Filled up the 90 yesterday after going to Curry and its been into the city to bring home the .,,.,,.,.,..,  Mustang.

Now indicates 11.9, still too high and I'm sure the Torque converter is not locking up.

Could be A/trans switch, or switch on the brake, or go peddle, since its had L - R conversion, (chain & bar or similar) maybe the switch is out of wack.

And YOU know how much I love Converters.

sabre:
No switches on brake or go pedal. All controlled by ECU. Spèed related only. Changed from about 70k in 86 87 to about 80k in 88. No idea of what speed programed for 90 model. No indication on my 88. Says nothing about it in handbook or manual.

Vettech:
Ummmm - the memory is not so good.

The 87 is knocked out of  Torque Lock if you hit or even touch the brake, I think this is designed  to stop engine stall.

The Torque lock I think can come on in any gear, my 87 definitely did it in both 3rd and 4th.

I have other issues now, with Alt / batt light coming on, so TCC etc is on back burner.

sabre:
I think you're confusing torque lock with cruise control lock.
