Ive got a problem with my nephew's 94 S-10 4 cyl automatic. Yestday he had the oil changed and tires rotated. Then driving home not far the tranny started to act up. It cluncks(?) into overdrive now it goes into reverse fine but clucks into odrive and the fluid smells burned.. They checked the fluid before the oil change and said it was fine.. Any help??

the level may be fine (check it your self)if it smells burned and is dark flush it out and new filter and fluid ,check your u-joint's also ,could be a coincidence after changing oil ,and rotating tire's .
