check engine code 11, coolant hot light flashes code 23, 95 SL2

[2003MercMaraude]

I have a 95 SL2 I am working on for a friend. She complained of a check engine light "and some other light" that she didn't remember, coming on intermittently.

Plugging the ALDL A&B pins together gives me code 11 on the check engine light, and code 23 on the coolant level/temp high light on the other side of the dash.

Code 11 looks like a transmission code but I can't find what code 23 on the coolant level/temp high light means. Hopefully it tells me more about what transmission fault is being reported.

Can anyone shed some light on this? Hopefully she does not have a major trans issue, I got rid of my 93 SL2 with less than 90k miles on it because after replacing the valve body twice I was never able to resolve harsh 1-2 part throttle upshifts. I thought the TAAT was supposed to be pretty durable!

Her car has only 81k on it too

Thanks

Steve

Thank you for that info. No 3rd gear, holy crap. That's not good. I have a spare reman valve body but I am sure as heck not going to change another TAAT valve body with an unsure probability of fixing anything.

The only things I can think of are to check the adjustment on the range selector, and to check to make sure the multi-pin plug that goes to the valve body, is not corroded or full of fluid.
