No overdrive in 99 Bonneville!!
Recently I bought a 99 Bonneville for 300 bucks to drive to work and back. I knew this before i bought it, but it doesn't shift into overdrive. Seems to shift fine into all other gears, and has no whining sounds or any other odd behavior. If i manually shift from od to d or d to od rpms do not change.The fluid looks ok and does not smell burnt. Not wanting to really put any money into this, I was just wondering if anyone had any suggestions.I have been reading about a tcc solenoid or stripped out splines on 4th gear, but i would greatly appreciate any other possibilities. If it seems to be an expensive fix, I will probably have some fun with this car in the demo derby this summer. Thanks for any info you may have.
