2006 Buick LaCrosse transmission problems could include shifting delays, grinding when accelerating, a feeling of shakiness, or whistling noises and a burning smell coming from under the hood.
With proper maintenance, a Buick should last around 200,000 miles on the road. Of course, factors such as age, mileage, and a Buick`s overall condition will go a long way in determining how long it can stay on the road.
Engine Oil

5W-30 (All TEMPS) – SAE 5W-30 is preferred.

Transmission Range Sensor (TR)/ Transmission Position Sensor

The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.

These LaCrosse models have been proven safe and investment-worthy as used vehicles. They have relatively few consumer complaints, have little to no major recalls, and should be considered an excellent option for car buyers on the market for a used Buick.
The 2019 Buick LaCrosse is a full-size entry-luxury sedan that can seat up to five people. It`s powered by a standard mild-hybrid drivetrain that uses a 194-horsepower, 2.5-liter four-cylinder engine and a six-speed automatic transmission.
It was the fastest series Buick ever produced, with a 0 to 60 mph (0- 97 kph) sprint time in 5.7 seconds and a top speed of 240 kph (150 mph).
The myBuick Mobile App enables you to use your smartphone to interact with your vehicle from wherever you are. You can remote start, unlock and lock your vehicle, view your fuel life and tire pressure and more on properly equipped vehicles.
The number one cause is the clutch components have worn out and no longer have enough friction material to overcome the weight of the vehicle. A second possibility is the transmission can be stuck in two gears at the same time and it won`t move. The shift mechanism can malfunction and keep you from selecting a gear.
Turn off your vehicle`s ignition and wait patiently for 5 to 10 seconds. Start the engine and allow it to idle for several seconds. Switch off the ignition and wait patiently for another 30 to 40 seconds. Repeat these steps 2 to 3 times in order to reset your vehicle`s transmission control module.
Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor`s wire coupling. Using the multimeter`s voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.
Using a variety of technologies and exterior enhancements, it delivers an estimated 36 mpg on the highway and 25 mpg in the city – a 20-percent improvement in highway mileage and a 32-percent boost in city mileage over previous models.
Paired with an eight-speed automatic, the smooth 3.6-liter V6 supplies plenty of power and a decent 24 mpg overall.
The biggest difference between Chevy and Buick is the level of luxury. Buick is going to be a couple of notches above Chevy as far as luxury and comfort go. If you want a ride that is both comfortable and technologically advanced without spending an arm and a leg, then a Buick SUV is going to be a great option for you.
The all-new 2024 Buick LaCrosse will make its world debut in the coming months in China, which will remain the only country where the nameplate is still manufactured and marketed.
In the North American market, Buick is a premium automobile brand, selling luxury vehicles positioned above GM`s mainstream brands, while priced below the flagship luxury Cadillac division.
According to Consumer Reports, while Buick is less reliable than Japanese automakers like Mazda and Toyota, it`s unequivocally the most reliable U.S. car brand – edging out brands like Ford and Chevrolet. J.D. Power also released its U.S. Vehicle Dependability Study in 2022.

the most relevant questions and answers related to your specific issue

My car want go drive but will go in reverse and shift in 1 or2 and drive some, so what could it be.
ANSWER : This is an internal transmission problem with the valve body or the 1-2 sprag unit binding internally in the transmission. Have a qualified transmission diagnose the problem firsthand to pinpoint what is going on. The mechanic may have to do a pressure test to isolate the cause of the shift concern.

I just got a new transmission put in my car and it drives and reverse but won’t go up hill.
ANSWER : This may be a sign of a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. I would recommend having an expert from YourMechanic come to your location to take the car for a test drive to more specifically determine the cause for this.

When car is shifted into drive car will not go forward when pressing gas it just rev the engine.But when shifted into reverse car
ANSWER : Hello, thank you for writing in. The color and condition of the transmission fluid should be a huge indicator. Low transmission fluid is one of the leading causes of issues with the transmission. You will want to start by refilling the transmission fluid, following manufacturer directions and specifications on the type and the amount of fluid. If this makes a difference, then you know the lack of good hydraulic fluid in the system was the immediate cause of your problems. This does not always mean that the transmission is not having other issues, as burnt fluid is not a good sign in a vehicle that is only 6 years old. Burnt fluid can also be a sign of how hard the vehicle is being driven. If filling the transmission with fresh fluid does not solve the issue, then the transmission needs to be inspected by a transmission specialist. Unless properly trained, automatic transmissions are incredibly difficult to work on at home.

The engine stalls when I put the car in reverse, but if I go past reverse into drive there is not an issue.
ANSWER : Hi there. Usually when you shift into reverse and engage the brake it will cause the engine RPM to drop; as it’s creating a load against the transmission and the engine. If the engine stalls, it may be caused by a faulty idle control valve, bad O2 sensors, or clogged fuel injectors.

In regards to the "pan", we’re not sure what you are referring, so it may be a good idea to contact one of our local professional mechanics to complete a battery inspection to determine what’s going on with your 2010 Ford Focus.

My pacifica runs and drives only reverse when i shift it to drive dies quickly . But you can shift it to reverse and neutral
ANSWER : This is an internal problem with the transmission and may be a valve body or leaking internal seal. The problem is the transmission leaking pressure internally, and when you put it in drive, the transmission is trying to go into reverse and drive at the same time causing the transmission to stall the engine. Have a mechanic, such as one from YourMechanic, scan the computer to see if a code is received that will help detect the cause. They will be able to diagnose your stalling issue, and any other problem you are having, so that a proper repair can be made.

Shifting issues from drive to reverse and back to drive
ANSWER : Mercedes has a dealer service order (#Order No: S-B-27.19/118A
) that addresses diagnosis, and possible dealer repair of the transmission for your model. Check with your dealer to confirm coverage of this.

My car will only shift into reverse and neutral, can’t get it into the drive gear
ANSWER : This may be a result of low transmission fluid or potentially a faulty transmission control module. A faulty transmission control module may cause a delay in acceleration or erratic shifting of gears. The transmission control module has various sensors such as vehicle speed sensors, wheel speed sensors, throttle position sensors, turbine speed sensor, and transmission fluid temperature sensors that all direct information to it in order for it to perform it’s function. Other functions controlled by the TCM are components such as a kick down switch, traction control system, and cruise control module. Any of these may also affect the way the transmission control module performs and controls the transmission and the shifting of your vehicle. I would suggest having a professional from Your Mechanic come to your location to properly diagnose your transmission problem.

My car will not shift out of drive and into park – 1999 Hyundai Sonata
ANSWER : Hi. This sounds like the ignition switch has a problem and is not allowing the car to go into park. If the ignition switch is not sending the signal to the neutral safety switch that the key is in the run position, it will not allow the shifter to move. It is also possible that the shift linkage is damaged and is causing the problem you have as well.

I suggest you have a certified technician, such as one from YourMechanic, come to your location to determine why the car is not shifting properly and suggest the necessary repairs
