1997 delta 88, transmission is not shifting to the overdrive gears Originally, my transmission was making a noise like a low flying helicopter. Took down the pan and found not only normal shavings but pea size bits of metals. So change out transmission and while taking it out of car, went ahead and changed out all the gaskets on the engine.
Car was running and shifting fine for the first 300 miles, then I had to go on a job about 100 miles from home, I noticed that the car was overheating and when I opened the hood and felt the top hose it collasped. So I bought a new hose and radiator fluid, but as I took off the hose, no fluid was coming out-so I opened the radiator to find it empty.
I changed out the hose and added fluid, but the radiator would not fill and the oil level was rising, the engine did a hydro-lock. Called a wrecker truck to haul the car in.
I removed the plenum, hand turned the crank after removing the spark plugs to get water out of cylinder, took the oil pan down and completely drained the engine of oil and cleaned oil pan. Did a fresh oil change, changed out spark plugs, replaced the plenum with new, installed new pvc. Started the car on the first try, test drove it down my drive way but did not take on road because it was late at night and would do in the morning.
Next morning, took the car on the road but no more than 500' feet noticed that the car did not do the normal shifting. Usually, the car will shift, go maybe to 2500 rpm and shift to the next gear-but it would not shift until maybe 4000 rpm-turned around and brought back into my shop.
I was looking at the vacuum modular to make sure vacuum hoses were secure and for leaks, the car started fine again, so again I went for a test drive, but again it would not shift in the proper pattern. Since I was on the road, I went to pay a bill about 2 miles down the road. The car would shift into the gears but not the normal overdrive with lower rpms
Usually at 70 mph, my car is about 2100rpm but it was over 3000rpm. I made my payment and as I was leaving the window the car stopped. It did thankfully start back up again but was running very rough, I inched home and as I turned down my driveway, no foot on accelerator the rpms was rising to about 2500 rpm, car running rough and black smoke coming from exhaust-pulled back into shop, turned car off and was not able to restart
I changed out all the vacuum lines except the one in the back that services the accesories.
The engine is running sweet, went back on the road to test it and it is still not shifting properly.
Before the original hydrolock problem the car was shifting fine, so now I am stuck and am not sure what to look for anymore to solve this shifting problem. In essence, I am not shifting into my overdrive gears
Oh yea, I did change the throttle body sensor when I changed out the plenum, the radiator fluid is fine and so is the oil.
Help! I need my car so I can go to work and I need it to run correctly as I am a contract Network engineer and when I get calls the clients networks are down and need to be brought back up ASAP and it does not look good when my vehicle goes down.
