i have a 95 seville sls trans seems smooth but never shifts from 1st just the faster you drive the higher the rpms get but no slipping. i drove the car on the highway never noticed any problems. i had a stud and tire changed after being on the lifts i started noticing the problem.what could be wrong

Start with checking fluid level.

Codes will come up using "Onboard Diagnostics" see faq section. Likely cause broken shift solenoid(s)
