Good news, at least for now. She's back on the road again. Shifts great, and the P0742 code has cleared itself. I do still have a stumble when going up slight inclines I haven't quite pinned down yet. Other than the rusted/frozen and broken bolts this really wasn't that bad especially considering I ...

Update
I've been working on this every couple days or so. Because the passenger side mount was bad I had to lower the sub-frame on that side. The front mount on that side did the same thing the drivers did (plate the nut is welded into started spinning) so I had to cut an access on that side too ...

Boy do I feel stupid. Upon further examination there is a big difference in this location on a HD transmission. There is no seat for a checkball on my trans like there is on a HD. The 1/4" ball would have just fallen into a channel and ended up who knows where. And the thing I thought was a ...

Thanks on the petroleum idea.
I got extremely lucky and found an image that shows exactly where the "extra" checkball is supposed to go. It happens to be related to the TC, so I expect I would have some issues if I left it out. The post is actually from this site, but the pics don't show up ...

I've replaced the solenoids and PCS in the valve body. The trouble is still in channel plate. The lower-left checkball isn't in the position it's supposed to be in the picture, but it looks like that one moves through a channel. Everything I've tried to get it out has been unsuccessful. Pulling ...

Finally got back to working on this tonight. I removed the transmission side cover, pump, pressure sensor and heard 3 things drop into a pan as I removed the valve body. My fear was those were the little 1/4" checkball valves. Indeed, I recovered 3 in my catch pan. According to my transmission ...

Good news. After some prayer and thought I pried up the keepers, opened up my access port and was able to get an adjustable wrench to stay on the nut. It still needed a lot of persuasion, resorted to heat followed by PB blaster and it finally came out. Whew! Reassembly shouldn't present too many ...

Here's the story. I have a 2000 Pontiac Bonneville SE - currently at 260k miles. At ~150k my torque converter clutch soleniod would ocassionally stick open. The "fix" was to pull over and shut the car off for about 10 seconds then the issue went away. After limping my transmission through several ...

I'm with Archon on this one. If airflow output is dropping there has to be something blocking the airflow. You might be able to feel around going through the filter housing. I can't remember if you can actually see the blower motor through this access or not but if you can, and the car is doing it ...

I figured it out!
After a little more review on these boards and due to the fact that shorting the relay pins was not engaging the starter, coupled with the highly scientific method of banging on the starter solenoid enabling the car to start I determined it must be the starter. It must have been a ...

About 3 months ago I began experiencing a no crank / no start issue. If I cycled the key repeatedly to start I could usually get it to start. After some review I convinced myself it had to be the ignition switch so I removed it, cleaned the contacts (they weren't really that dirty but at 220,000 ...

Something similar happened shortly after I purchased my 2000 SE last year - I heard water moving in the HVAC system while turning. I found the evaporator drain off a site for the Grand Prix but ours is basically in the same place. From under the car follow the exhaust down along the firewall - the ...
