Hello,

My Tune has been running fantastic but recently what I thought was some "hunting" or "hesitation" mid-throttle turned out to be the TCC sort of locking and un locking and in general doing nothing super positive.

It will lock solid later (at higher speeds) or if I back of the gas -- and if I punch it- it will quit trying to lock... so overall it is good at the extremes but the middle ground has gotten squishy.

I am running a 454 with a 4L60E tranny so a little extra torque on the front end. The tranny is build strong and the TC is supposedly pretty good... but I am wondering if this is an indication of a tune issue / sensor issue or if maybe some failure of the TCC might be happening.

Any thoughts welcome.

Also, if anyone is interested- I have a 91 454 MEMCAL available if anyone wants to make an offer. Cheap is OK.

KV.
