We have all heard the click tick, piston slap on some, others had bad lifters ect.

One day I pulled the truck up and decided to add some Lucas trans fluid stuff. The sound stopped.

I had had just been living with the whole cold motor piston slap from the dealer jive.

A 32 oz bottle of Lucas and 1/2 a quart of d6 later I discovered the quick lube I had it flushed at only filled a hot transmission and fluid to the top of the cold mark. Once warmed up good it barley made the bottom of the hot line, and quieted down.

Cold it it would seem to be just a touch shy on the stick but in the hash.

Might be worth checking if anyone else has the tick and had service done.
