Hi, new here. Hopefully this wasn't already covered.

Installed new lead frame board, along with new bulk head sleeve and the Rectangular fitting.

Refilled with the transmission fluid.

Let it get up to temperature, roughly 190ish.

Checked and topped off appropriately.

Went to drive it, but it suddenly shifts from 1st to 5th. Then tries to correct itself and goes to 3rd/4th.

Won't shift further down than 2nd, won't go further up than 5th.

Both ***** are lined up properly. Connections are tight. Is there something I may have missed?

Thanks for your help

What kind of lead frame did you put in? Motorcraft or other?

90% of the stiff on Amazon is garbage. And a certain percent of known brand
merchandise is counterfeit. I would only buy from a well recognized seller.

Buy from a Ford dealer - either local or on-line. Best way to ensure you are not getting counterfeit parts.

I got burned bad buying on line...bought a set of "Genuine OEM Motorcraft Spark Plugs" that sure appeared to be OEM - all in boxes marked like in any other Motorcraft spark plug, and the markings on the spark plugs appeared genuine. Center electrodes melted away in 2000 miles. Counterfeit repair items are a huge problem right now - lots of YouTube videos about it on line. No just spark plugs but all sorts of repair/replacement stuff. These items may appear to be OEM but are made of inferior materials!
