Unfortunately, servicing a high-mileage transmission can cause issues if it's 'flushed'. It actually flushes out the the gunk (old fluid) that keeps the seals from leaking. If they flushed it vs. just draining and refilling w/new fluid this may be what happened.

I wouldn't repair or get a new transmission unless you intend to keep if for a long time - another 30K miles+. I'd suggest a used transmission, which should be much cheaper. If you can find a shop to install it, they can also warranty the install and the transmission - most all used parts stores (junkyards/wrecking yards/etc.) warranty their parts, too.

''04 Buick LaSabre, Transmission rough shifting. Are pressure control solenoid and shift solenoids internal to transmission?


The solenoids are internal ! But if it were a solenoid problem the check engine light would come on . There are a lot of variables involved in the shifting of electroniclly controlled transmissions , it's all part of the engine management strategy programmed into the PCM - engine computer . I would take and have it checked before guessing about parts problems . A good qualified repair shop would hook up a professional grade diagnostic tool and road test the vehicle . With-in a few miles they would know for certain .

Pass front wheel vibration 2003 Buick Lasabre with 120K onit. At 55-70 MPH. New tires on it. New bearing/hub at 95K miles.New ball joint and control arm. New tires, Rotated and Rebalanced.


when you rotate the tires and their is no change check the c/v axle -and hub 25k is not considered new have changed hubs that have gone bad at 10k -look into ball joints,upper lower bushings ,tie rod,struts the latter can cause vibration but usually at all speeds

1999 buick lasabre turns over but wont start


Fuel mixture issue, several possible causes except the starter which uses electricity from the battery to spin the cylinders and eliminate static inertia. It could be flooded, out of fuel, bad MAP, etc. 1999 is old but probably still modern enough that it is fuel injection and not spark plugs. My Prizm is from 1999. It's junk but will last another 120K miles.

On ocassion, my 1998 LaSabre (with 91,000 miles) won't back up when I shift into reverse. Transmission need replacing?


you need to have the transmission serviced and checked for broken gears. There is a chance its slipping and not locking into place when you shift because of a broken gear and this could cause more issues if not looked at soon. parts break and get jammed inside causing further damage. Take it to a reputable shop and have it checked soon.

Diagram for 1998 buick lasabre serpentine belt


I found the diagram in my owner's manual.
I replaced the belt on mine just 2 days ago. All you need to do is remove one bolt from the lower motor mount and remove the spacer. After you relieve the belt tensioner, the belt will slip right through the gap. Don't forget to support the engine before removing the bolt. As a backup I took a photo of the belt with my digital camera beforehand... just in case.

97 buick lasabre trans slips in overdrive


Either the cruise control is going out or the torque converter clutch circuit is going out on the trannys overdrive. Do you have check engine light codes? If so you will need to have a computer hooked up to read them. Darrel coleman also has a problem with his car like this and I have suggested the same thing to him

Service on a 2003 fx35 with 120k miles


Well if you ask Infiniti, everything. From belts to flushing all the fluids and of course plugs and wires. Estimated at $1,000.00 for the works. I would flush the trans. oil and the anti freeze, as well as spark plugs. Also check the belts to make sure no visible cracks.
