97 won't shift out of first
I have a 97 lesabre that just recently hydro locked. I fixed that got everything back together, and now it won't shift out of first. The tranny has never had any issues, it only has 98000 on it. I've checked the vacuum and the plugs to the tranny everything looks good. Please help.

I assume you did not remove the motor and only replaced the UIM/LIM.
A good place to start would be having it scanned with a decent scanner.
Are there are any stored transmission or other stored codes present?
When was the last time transmission was serviced/pan drop & filter?
Fluid level in transmission correct?

Yes I only changed the uim, and the lim. I had it scanned, the scanner said pedal position sensor. I replaced the the throttle position sensor. Which didn't fix the problem. Transmission was serviced 20000 miles ago. Would the transmission have a pedal position sensor?

You mean throttle position sensor? I'm wondering if it was installed "incorrectly"? If its not installed right, it will give false readings and the PCM does use the TPS sensor for shifting.
My video explains how to install one correctly.

So reinstalling it fixed the issue?
