Hello. My 1151A1 has 2 transmission relays. The trans light is off , I can't get any code, trans is stock in 2nd gear. Does any one has 2 relays?

Do you have voltage going into and out of the relays? Also voltage into and out of the breaker?

This thread should help, has wiring diagrams with wire numbers too. Has the wire numbers as well, it’s easy to follow:

The relay is universa, it’s designed to switch on 12v when 24v is supplied in the case of the Trans relay, the other Relay is for windshield de-icer or AFES, can’t remember which one at the moment. We remove all that extra wiring as it’s no longer needed, the transmission TCM power runs through them on 29T Which is relay wire #2, if 29T is not plugged in or cut? You will be in limp mode

Hello guys. Sorry, I could not reply sooner (I was swamped during the week). I appreciate all the support from you a LOT. I do this project mostly during the weekend. Here is an update: I have 12V on pin Z, I have ground on pins a and b on J1 connector. On J2 connector: I have ground on A and F and 12V on D. Here is a picture: there are two 29 T in this compartment, one (29T) and another with (J12 29T P32A). Which one should be connected to wire 2 on the relay?
