Transmission is about 1/2 dead.

Transmission is about 1/2 dead.
For starters it'* a 1994 model with 91,000 miles on it (non supercharged). Usually if I leave it in overdrive and cruise along steadily it will kick into overdrive at 50mph or a little less. Tonight coming home from work all was good and it was shifting fine. I slowed down and changed roads and started up a hill. I always put it in drive up this hill cause it'* not very steep and sometimes wants to shift into overdrive (then it doesn't have enough power and downshifts again so basically I'm trying to save it some shifting). Anyways, I crest the hill and put it in overdrive and it shifts fine. I start coasting down the hill for about 1/2 mile or so and give it a little gas and the RPM'* hang around 2,500. After a couple seconds it was obvious it had no plans on shifting and it was stuck in 3rd gear. And of course in 3rd gear the torque converter doesn't lock up so that'* really heating up the tranny more than I want it to. I speed up a little hoping it was just a glitch but nope, even at 70mph it was still in 3rd gear and wouldn't shift. If I let off the gas going 50mph or so the RPM'* drop down to idle then bump up to about 1,500 or wherever the RPM'* would normally be in overdrive at that particular speed. Once I hit the gas again it'* still in 3rd gear. Now if I stop, the car takes off in 1st, shifts to 2nd and into 3rd fine but it won't go into 4th or overdrive to save it'* life. I'm hoping a cable or something came loose but it'* 4a.m. so I'll check it tomorrow. In the mean time please post anything that might help me out. Thanks,
Jason

First off check you tranny fluid. Hows the level, color, condition?
When was the last time you had the tranny serviced? Maybe you need a flush and new filter?

Had the tranny flushed and a new filter put in about 5,000 miles ago. It'* at the shop now, we'll see what they say. I'm hoping it'* something simple, really don't want to spend the money to get the transmission rebuilt.

Picked the car back up Friday evening. My dad took it to a local trans shop and said it shifted fine on the way there. I called the shop before going to work and they said it also shifted fine for them. He also said he did pull a couple of codes out of the computer that lead him to think it'* the valve control body. He said I might have been lucky and it was just a piece of dirt that got stuck and is now gone or it could be starting to go bad. He also said that usually when they go bad the car will be in 4th or overdrive and then start kicking out of those gears into 3rd gear. Anyways, we picked the car up and I'm going to drive it around this weekend and give the trans shop a call back on Monday. Might just trade it in Saturday if it'* shifting good, who knows. And he said that replacing the valve body including labor would be in the $400+ range depending on how much the parts cost. I really don't want to put any more money into a car that I don't enjoy driving. Most likey trading it in or selling it back to my dad for $2,500.

Mine has been doing the same thing for almost 3 years now. After i cruise on the hwy for a while, or even around town it won't go into 4th anymore. I haven't got it checked out or fixed. She'* go 120,000 on her, if tranny goes.. she'* gone.

I drove it around for about 30 miles today and it did fine so who knows, hopefully it fixed itself. I put a bid in on ebay for a car so if I win it the Bonerville is gone.

Theres a problem with the valve bodies on 97 bonnies...ive read the tsb'* [technical service bulletins] stating that the dealer replace the valve body with an updated design.....i have a 97 which apparently fell through the cracks...and is shifting roughly into o.d...out of warranty at 101,000 miles....there was a warranty stated...i cant remember what it was....i got the info at NHTSA.....this is a beautiful car except for this one flaw...i found that if I accelerate briskly.....it will shift smoothly..but a slower acceleration yields a rough shift/lockup.......its akeeper anyway[had it for a year..no other major problems]
