I'm trying to remove the transmission fluid pan to replace the transmission filter. After draining most of the fluid and removing all the bolts, I thought it would as simple as dropping it and sliding it sideways, but the exhaust pipe seems to be in the way. Is there a way to remove it without removing anything else or am I missing some steps.

the front driver is making a noise,

It has 200,000 k. Are there any other issues i need to be concerned with.

i was driving on the freeway and all of a sudden it started slowing down as if it had turned off and i put it in park and turned it off and turned it on again. i dont know about cars so i took it to jiffy lube to get an oil change and surely enough it had none whatsever. but when i left jiffy lube it once again decided to turn off. i tried turning it on and it wouldnt anymore at all and thats when "stability system diabled" came on.

will move in 1st and then runs fine and sounds fine after shifts to 2nd. what are possible causes and likely fixes.

the engine light just came on...

any online sites specializing in autmatic transmission and its eletrical components of a 1999 yucon denali that render the transmission to not having any gears i had a transmission blow its clutch making a terrible noise this time it just stopped working barely a noise when it went almost a disengage noise then no more noises and no more movement 2 or 4 wheel drive leading me to believe its eletrical some eletrical component names may help in my trouble shooting

i changed my transmission! 1st problem motor wouldnt start unless i went to starter. seems the small wire no longer worked. i figured we pinched it. so we ran another wire to crank fuse.it only had power when starting truck.i noticed gear shift light was out!(whatever)so anyway it worked this way for a week.then a quiet clank and then i lost all gears at about 10 mph.when i shift threw gears motor idle doesnt change what happened?please tell me!i would rather change an eletrical part than the whole transmission! thanks for any suggestions.

My gas tank suddenly has become very slow to fill when refueling. I was told that it is likely a stuck tank vent valve.

Just stopped opening one day. Took it to the dealership and had disagnostic test done- showed nothing was wrong. Fuses were checked with no issues. The dealership said they would replace the entire back door locks for $500, but still couldn't guarantee that it would solve the problem. What else can i do?
