If the transmission fluid level in your Jimmy is low, you need to add transmission fluid through the dipstick tube. Be sure to add only a small amount at a time. I added 4 quarts + a little more, which was the amount that came out. I added 4 quarts + a little more, which was the amount that came out. I'm sure every car is different.
It must have not been pushed in far enough the first time, so it fell out. At least there's no bubbles in it this time. I did it that way on an '02 Chevy 1-ton 195K miles 18 times, no problems. Close the hood of the Jimmy. This transmission repair shop said that this is common with the Jimmy, as well as a faulty gas gauge, faulty ball joints and oxygen sensors. Black fluid would likely be clutch material that wears off over time.
Install a few bolts by hand so pan will stay up by itself, then install remaining bolts. Sorry to be so ignorant but, what exactly does this cable do? It appeared to be locked in place. It did take quite a few turns, and getting it started back was tricky. One lesson I've learned is don't replace that seal that goes up into the transmission that the filter pushes into unless it's physically damaged. I could not remove the trans pan.
If you have a wratcheting wrench you'll be happy. The 305 should hold 5 quarts of oil I believe. The cooling lines are there to cool the tranny fluid, and it is circulated through the radiator by means of a pump. I want a recall on this problem. Shop will possibly rebuild and use aftermarket kit parts to correct problems the transmission had originally. Once the transplate was loosened, everthing slid back perfectly.
Once I finally got that out, the rest went fine. If a line is leaking, the pump will just empty the fluid out through the leak. I taped to brake to turn off the cruise control. If your sun shield has terrorized your tranny, you'll be able to tell. Sounds to me like there is a lot of crud built up in it and another change would probably do the trick. Good luck I got the same problem on a 97 Jimmy and 3 shops said the same thing.
Clean off magnet in the pan, clean off gasket mating surfaces on pan and trans. The new trains filter will should come with a new gasket, unless your truck was equipped with a reusable one. I am using ramps to raise the front of the truck. Socket extensions and deep sockets come in handy. The only remaining question mark is the fluid level.
I tried working it in, but all I got was a warped seal with the rubber coming off. Your transmisison dipstick will also tell you what type to use, along with the owners manual. When you get to the front 4-6 bolts, back them out less than half-way so the fluid will start to run out the rear of the pan. It really wasn't a good time when I realized that the seal was loose and had to repeat the process over again. After resuming the cruise control the vehicle began picking up speed much to fast. Then work your way toward the front by removing 1 at a time from each side.
To check the fluid level,jack up both ends of the vehicle and be sure to support with jack stands. I assumed when I had bubbles in the fluid that I had overfilled the fluid, but 4 quarts went out, and 4 went in, so it's definitely the lack of an installed seal causing the airation. If not, you're good, just throw the new filter right in. Then use a swivel on the extension. Interestingly enough when I dropped the pan, the old filter and seal were in the pan and not installed.
