91 R/T won't shift

I have a 91 R/T that won't shift. It seems as if it is stuck in limp mode. I cannot manually shift it and it takes off real slow like it is in third gear. Anybody had this problem?

Thanks,

"like limp mode". perhaps it's actually in limp mode?

I'm with Steve on this one. Plug 'er in and see what it says.

Well hopefully I can get my hands on a TCU and see if this is my problem.

Ok, so I pulled the tcu and sent it out for repair. I picked up a used one from a guy locally who had a 91 R/T with about 130k. He said he had no issues with the trans. However, I had the ECU rebuilt and it runs fine, better even. The trans is still stuck in limp mode! WTF! How can I have another bad tcu? Anything else I should look at?

Thanks,

it might actually be dying. excessive metal shavings in the pan?

Well, the kid I bought it from said he just had the trans flushed. The fluid is clean and it was waaaaaaaaay overfull! I draid about 3qts and it's still a lil over the hot mark...not too much 1/8". No shavings from I can see. I should be getting my rebuilt tcu back this week. If I still have the same problem I may have to pull the pan and see my nightmare!

kid could have flushed it to try and "cover up" whatever was wrong with it. can't say for certain though. i've heard many stories about kids doing neutral-drops with an ATX. i wouldn't put it past teenage dumbass.
