2003 Buick LeSabre

259,461 miles. Engine runs, but it doesnt move...unless you like reverse. Ive owned since about July 2017 when mileage approx 69,500. I've put almost 190,000 additional on it. Lots of small issues and one big one. The car won't work in any forward gear. It was working its last mobile days in first and second, but then deserted me. Transmission has been acting up probably for last 50,000 mi, but was always driveable. Now its shot. Also, I do have engine light with trouble codes which suggests intake gaskets leaking...even though I replaced those with the upper intake manifold and other parts shortly after I bought the car. Theres no leaking of coolant into oil. I was at a time losing coolant...which Kseal helped. I've kept a log on everything Ive replaced on the car since I bought. I'll list some of the newer item replacement below, but recent ones have been new starter, radiator, oil pressure sending unit, water pump. A/C compressor may be failing and blend door needs repair as hot air blowing from two vents, and barely cool air from the other two. I put my gauges to it, and Google AI said don't add any coolant...your compressor is probably failing....so I haven't. AI is not always correct however, as you know 🤔 Driver side rear window needs regulator. Passenger side front window and door lock do not work. I think the wires have broken going into the door where they bend inside the rubber bellows. Interior lights not working either. Front headlight cover a bit cracked and askew where someone clipped me a while back. Paint and body is in really good shape. Radio, CD, Tape all work. Headliner replaced several years ago, no sag...but not pristine looking. I'll get some more interior pics when (/IF) I get it cleaned out. I replaced all front end parts at some point except for inner ball joints. Front end may need attention however now since driver side front is wearing (photo). Passenger side tire not so bad. Looks like power steering rack boots need replacing. Almost forgot...the rear air shocks were replaced with coil over spring. The compressor was still good at the time I did that. Definitely needs an oil change. Clean title. No liens. I'm keeping my plates. A Partial List of replacements back 3 yrs: 8/5/26 idle air control valve 5/27/26 all ignition coils 4/23/26.
