I just put a 700r4 in my '88 Monte Carlo SS last week after i blew the stock 2004r. The tranny has been great up until yesterday. It was working all day, then when i left work, it wouldn't shift out of any gear until the engine redlined. I went home, checked the linkages, and they were good, but i didn't show any fluid on the dipstick, i added 2 quarts, and it was back up to full. But there was no change in the trans. The funny thing is that i was having the same problem with the 200 before it finally blew 3rd gear. Any ideas...let me know.

First things first: To adjust the TV Cable skip the book method and do this: Press the D button on the adjuster and loosen the cable setting. Now, have someone floor the gas pedal while you check to see if the throttle plate is open all the way. Usually they are off a little and will wiggle. Do whatever you have to do to get it open solid. Now, with the pedal still floored, press the D button and pull the cable casing (the black tube) back as hard as you can and release the button. You now have the engine, tranny and gas pedal all in sync at WOT. Mark the cable so if for some reason it gets moved you can know where to put it again. The problem with the 'self adjust method' is that it bends things and puts them permanently out of whack. It is also the full TV setting, which is theoretically what the GM method does.

By the way, do yo still have the 200-4R? IF so what are you doing with it (yes, I know it is burned up)?
