Not shifting into 4th gear

2006 H2 transmition problem. first, second,third and OD work as long as I shift manually. If I put it in Drive from a stop it will not move. If on the highway I pull a hill and it shifts by itself into 4th it will just rev the engine until it hits the shut off.

My H2 is currently in the shop for a very similar thing. It would not shift correctly and it seem to be stuck in 4WL. This first time this happened it was a sensor. With labor (not at dealer) this cost us about 500. This time it turns out to be a problem with the transfer case. At first we thought it was a sensor but it turned out that there is a "fork" in the transfer case that had broken. To fix we are hunting a used transfer case which runs about 800-1000 bucks. New from the dealer runs about 2200.

SOURCE: 02 jeep liberty won't shift into 3rd or 4th gear.

Ratio codes generally indicate a pressure loss & slipping which the computer reads as a gear ratio problem. Likely you need a rebuild.

SOURCE: 1995 cadilac deville has problem shifting from 1 to 2 gear

You don't have torque converter shudder. You don't even mention that in your original post! You def had a solenoid issue. My 94 STS did the same thing. I only had reverse, 1st and 2nd gear. Wouldn't shift outa 2nd period. It was a $200 solenoid repair. Car had a 160K on it when that happened. I have almost 170k on it now. Shifts and works fine. you don't need the tranny replaces ad josavv63 indicates.

SOURCE: 2003 honda pilot won't shift into drive

On my Honda Pilot I experienced the same problem having difficulty changing the gear shifter from park to drive. I drove it to my Honda dealer and the technician explained that the problem was a brake sensor was worn and needed to be replaced. This is because the brakes must be engaged before shifting from park into drive and that the sensor gets worn over time. As I remember, the sensor and labor to install was somewhere between $25 to $50 to replace. It now works like a charm.

Oil Filter Assembly
• The oil filter assembly (100) is missing, plugged, or damaged.
• The oil filter seal assembly (101) is missing or is damaged.

Control Valve Body Assembly
• The 3-4 shift valve (362) or the 4-3 manual downshift valve (360) is stuck or binding.
• Debris is found in the passages of the control valve body (301) or of the control valve body spacer plate and gasket assembly (396)

Case Cover Assembly
Distortion or damage occurs at the manual valve (404) or at the case cover (401), causing PRN oil leak.

You have internal transmission damage I expect the clutches on third and fourth gear are wiped out. Its either that or a solenoid gone bad that holds those clutches pressure get it in a transmission shop soon to avoid whole transmission replacement costs.

2004 is not sifting into drive doesnot slip it just dont sift


Is it not shifting into OD? It should shift from first to second, then second to third, and third into fourth which is od. I'm not quit sure which forward gear you are meaning.

Transmission is shifting hard and slow to pull on a 95 silouette also makes clucking sounds while accelerating


Shift suddenly become very hard. When going from park to either reverse or drive it slams into gear. 1-2 and 2-3 shifts are also harsh. All gears seems to work. Problem may be intermittent: Check TPS for smooth and linear electrical response over the entire range of motion. If not, replace.

Extremely harsh shifts from P or N, normal shifts at WOT: EPC (Electronic Pressure Control) solenoid failed. Easy fix in pan. Fix as soon as possible or hard parts will eventually break.

No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Car goes into gear but feels very sluggish like the brakes are dragging, but it will roll easily (starts out in 4th gear), you manually shift to 2 to get it moving, once it's moving you put it back in OD and the car shifts 3rd to 4th on its own and locks the converter at the appropriate time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Only runs in 1st and 2nd gear and reverse.


This is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.

Trans shifts into gear harshly, car feels sluggish off the line
, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the under hood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.

Transmission does not shift automatically, only manually. Swap in a known-good PCM, check wiring, check other sensors such as VSS and TPS.

Down shifting


if you are going to fast and down shift of course its a grind maybe your suppose to be on 4th gear not third gear so that means you need to shift to 3rd.
