My blazer is having hard shifts between 1st and 2nd gear, sometimes I can shift between all gears no problem, next just 1st and 2nd… Than none at all, each time a gear disappears its like my blazer is in neutral. Problems with reverse and the issues only seem to happen when the temp gauge is reading at least 195+. Also really tgin trans fluis almost like water was added. Please help!
If the transmission fluid level is full and the fluid looks clean it would indicate an internal issue. Most likely a sticking solenoid or failing solenoid.
Automatic Transmission Operation
Your automatic transmission may have a shift lever located on the console between the seats or on the steering column.
There are several different positions for your shift lever.
If your vehicle is equipped with a column shift lever, it features an electronic shift position indicator within the instrument panel cluster. This display must be powered anytime the shift lever is capable of being moved out of PARK (P). This means that if your key is in OFF, but not locked, there will be a small current drain on your battery which could discharge your battery over a period of time. If you need to leave your key in the ignition in OFF for an extended period, it is recommended that you disconnect the battery cable from the battery to prevent discharging your battery.
- PARK (P)
- This position locks your rear wheels. It’s the best position to use when you start your engine because your vehicle can’t move easily.
Warning! It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park . If you are pulling a trailer, see Towing a Trailer .
Warning! If you have four-wheel drive, your vehicle will be free to roll — even if your shift lever is in PARK (P) — if your transfer case is in NEUTRAL. So, be sure the transfer case is in a drive gear — not in NEUTRAL. See Four-Wheel Drive . See Shifting Into Park (P) .
Ensure the shift lever is fully in PARK (P) before starting the engine. Your vehicle has an automatic transmission shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition key is in RUN. If you cannot shift out of PARK (P), ease pressure on the shift lever; then, while pressing the button on the console shift lever, push the shift lever all the way in PARK (P) as you maintain brake application. Then move the shift lever into the gear you wish. See Shifting Out of Park (P) .
- REVERSE (R)
- Use this gear to back up.
Caution! Shifting to R (Reverse) while the vehicle is moving forward could damage the transmission. The repairs would not be covered by the vehicle warranty. Shift to R (Reverse) only after the vehicle is stopped.
To rock your vehicle back and forth to get out of snow, ice or sand without damaging your transmission, see If You Are Stuck: In Sand, Mud, Ice or Snow .
- NEUTRAL (N)
- In this position, your engine doesn’t connect with the wheels. To restart when you’re already moving, use NEUTRAL (N) only.
Warning! Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, the vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while the engine is running at high speed.
Caution! Shifting out of P (Park) or N (Neutral) with the engine running at high speed may damage the transmission. The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle.
- DRIVE (D)
- This position is for normal driving. If you need more power for passing, and you’re:
- Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down.
- Going about 35 mph (55 km/h) or more, push the accelerator all the way down.
You’ll shift down to the next gear and have more power.
DRIVE (D) should not be used when towing a trailer, carrying a heavy load, driving on steep hills or for off-road driving. Select THIRD (3) when operating the vehicle under any of these conditions.
- THIRD (3)
- This position is also used for normal driving. It offers more power and lower fuel economy than DRIVE (D). You should use THIRD (3) when towing a trailer, carrying a heavy load, driving on steep hills or winding roads or for off-road driving.
- SECOND (2)
- This position gives you more power but lower fuel economy than THIRD (3). You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on.
You can also use SECOND (2) for starting your vehicle from a stop on slippery road surfaces.
- FIRST (1)
- This position gives you even more power but lower fuel economy than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1) while the vehicle is moving forward, the transmission won’t shift into first gear until the vehicle is going slowly enough.
Caution! Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by your warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place.
