trans prog issue
My car recently has given me the trans prog a few times. Originally, it was due to low fluid, because my dumbass friend re-used my old gasket when we did my trans filter, and it leaked everywhere. I replaced it with a new one, refilled and everything was fine. On the way home from work today, after warming up and cruisign at ~40 for 5 minutes or so, the trans prog came on. I turned the car off, and then immediately re started it, and drove 8 more minutes home with no trans prog issues. The car runs good, and it seems random. I read the e34.net article on the trans prog, but i dont know where to start. I read the fuel pump relay/fuse may affect it, think this could also cause me hesitant starting intermittently? Thanks!

if you have never replace the DME and fuel pump relays, do it.
your car will thank you.

could you please tell me where those relays are located? i looked at my fuse panel, but i couldnt find anything on the cover that named the larger relays, only the fuses.

You can search further for "fuel pump relay" in the forum as there had been a few pictures posted in threads questioning identification which of the three or two found in the box it happens to be...
