Replacement Diode for 93 AW4 Transmission TCM

I have a question about a part on the board of a TCM for a AW4 automatic transmission out of a 93 Jeep Cherokee.

I was cleaning the board and I saw one of the connections was broke. What kind of diode/resistor is black, 1 blue band and has a 7 7 on one side and a T on the other.

I cant find what the amps on it would be or any information about it.

Is the blue band at the very end and there are no other stripes/bands going around it? If so that's a diode, the blue-end is indicating the cathode end. A 12v rating is enough, I'd be happy with a diode rated to 5 amps or so, or the biggest ampere rating you can find that will replace it and fit into its mounting position on the circuit board. Make sure you position the replacement diode so its striped/cathode end is positioned as your present one is.

When you have a choice, buy American made.
