I just picked up a 97 Caravan sport 3.3 from a family member. I was told that the car wouldn't shift into OD sometimes. The car was taken to a dealership before it was given to me for a tranny flush. The dealer said that there was no excess metal shavings in the pan.
Anyway, the car was fine at first but then the other day it wouldn't upshift. At 50mph the car was reving to 4-5K. I pulled over turned the car off, immedietly turned it on again and the thing shifted fine. I figured I should pull the codes since my indicator light was on.The 3 codes I got were P0700, P0740, P1776. One seems to be a tranny control code, ones a torque converter circuit failure and the other I'm not sure about. It seems like it is either a ignition retard timeout or a solenoid problem. What do you guys suggest I start with? From reading the boards it seems like I should look into the solenoid pack and the tranny ECM. Any other suggestions? Is there any way for me to pull the tranny codes myself (I use the codereader at Autozone)? Could the torque converter code be anything except a mechanical probelm with the converter?
Other problems I've experienced with the car are a slightly harsh downshift, an annoying vibration when cruising between 75-85mph and a weird scraping type sound. The sound occurs most when I turn the wheel slightly and accelerate lightly. The noise also shows up when accelerating lightly off of a light but only sometimes. Today the car also made a slightly similar but much quiter version of the noise when i put the car in gear (D and reverse). It went away when I put the car in park or nuetral. Any opinions on these problems (which may or may not be related) would be great too.
Sorry for the long first post guys.
