Some of you may have read my earlier post about not having 2nd and 5th gear on my 2000 LS8. Well, I finally pulled my pan a couple of days ago and looked at my fluid. It was awful looking. It was a very dark brown and full of metal flakes. Some of the flakes looked like aluminum or steel and some looked like copper or brass. If the fluid had been clean I was going to replace the solenoid pack. However, it appears I have a hard part failure of some type.
I now have the transmission ready to pull but I can't seem to break it free from the engine. I really don't like yanking on it with the car up on jack stands all around. I think I have every thing disconnected. 16 housing bolts, 8 torque converter nuts, the front driveshaft half is dropped, the trans mount is out, the cooling lines are disconnected, the exhaust is off, all of the electrical connectors are off. I believe the guide pins are corroded but I want to be sure. Did I miss anything? Any help would be appreciated. Thanks
 
put a jack stand under the oil pan with a block of wood. Lower the trans enough so that the jack is barely holding it. Then lift the trans up tail shaft, so the oil pan presses against the block of wood/jack stand, wiggle the trans up and down and side to side.

be carefull, you can pry against the bell housing carefully to try and free it as well.

I cant remember off hand but I know the V6 has 2 bolts on both sides of the bell housing that are bolted on from the opposite side. I really dont think the V8 has them though.

Jay,
I will look for bolts from the opposite sid and thanks for the tip.

Quik,
Thanks for the link.
 
Leave a couple of bolts in the bellhousing!! You can screw them in far enough to hold the tranny's weight, but still have enough play to allow the trans to move and break free. Once loose, then completely remove the bolts and lower it. I have seen two guys seriously hurt by stuck trannys falling on them.....
 
2001LS8Sport,

Thanks for the safety tip. I already had that one covered. I am an old fart so I have done a few transmission swaps. This trans seems especially hard to break free though. I thought maybe I was missing something. I just hate rocking the crap out of the tranny with the car up on jack stands.
The next house I buy is going to have a garage with 12ft ceilings and a four post lift.
 
I got the tranny out today and installed the used one with 19k. I appreciate the help you guys offered. I wasn't smacking it hard enough. I finally broke it free by laying on my side and kicking the tailshaft very hard from the sides. I think my biggest hassle now will be getting the fluid level correct.
 
hey fishbone how did you go about backflushing the cooler and lines??? in need of doing this myself so would appreciate your response.
 
beaups,

I have a little hand operated pump for bleeding brakes and testing vacum. I am going to try to use that to flush the old fluid out of the cooler and lines.
 
wow sounds risky. I've heard you really need some pressure and heat/vibraton to clean all of the debris out of those lines.
 
I am pretty sure it will be ok. If my tranny was still working in 1st, 3rd, and 4th with the sludge that was running through it. The few little flakes that I leave behind in the cooler should be no problem at all for it. Especially with a new filter and new fluid in it. Also, I was considering driving it straigh to the Dealership and having them flush it after I get it back together.
 
hey one more thing. service manual states that when replacing ANY transmission in this car after failure that you MUST install an in-line filter...probably to grab and crap that finds it's way out of the cooler. just an fyi...
 
beaups,

Thanks for the info on the filter and flushing the cooler. I think I will try to find a few cans of aerosol cooler flush. That will be better than doing nothing at all. I will have to search to see what type of inline filter I can install also.
