Transmission will not shift into 3rd or Drive
\015 The truck will run in 1st and 2nd gear, but will not shift into 3rd or Drive. It will go into park and reverse as well. I do not have any check ingine lights on, and the fluid is full. It is, however, dark. The trailblazer has 200,000 miles on it. When in 3rd and drive, the rpm's just rev with no exceleration. Any advice would be greatly appreciated.\015

Shifting problem Automatic transmission in a 1998 Civic LX (w/145k) has a shifting problem between 2nd and 3rd gear. The shift will be not smooth and takes a second to engage into 3rd. Though if I drive harder and have it shift over 4500 RPM into 3rd, it will shift cleanly. I did a quick look at the transmission fluid, the level looks fine, the color is light red. The transmission jumps/surges when it shifts from 2nd to 3rd, but only if it shifts below 4500 RPM. It is not a clean shift i

I have a 1995 Nissan SE V6 pickup with an automatic transmission. The transmission is in 3rd gear when you put it into drive with it stuck in 3rd with no downshift or upshift, but if you pull it down into 1st (before you drive much distance) it will go into 1st. After you start driving you shift into 2nd and it goes to 3rd, in overdrive it also stays in 3rd. If you come to a stop after enough distance to really get the fluids flowing, and you pull it down into 1st again to take off it is in 2nd.

Hi, I have a 2005 Hyundai Tiburon GT V6 and I recently had the transmission replaced (two days ago). They told me that the transmission would shift hard for awhile until it learned my driving. I've driven it about 50-60 miles so far and the shift from 1st to 2nd is nice and smooth and the shift from 3rd to 4th is nice and smooth. The problem is going from 2nd to 3rd it shifts so hard that it jerks me forward. It's harder at lower RPM's but even up to 4,000 it's still fairly noticeable although l
This is not normal transmission operation, they are mistaken about the learning capability of the trans, yes the system can learn your driving habits, this takes about 50 miles or so of mixed driving, these are very slight changes to the way the tran ... 2005 Hyundai Tiburon
I have a 2002 f150 and the code P1121 comes up on the code reader. Will this have any effect on the Transmission? When I started driving the truck, I shifted it in Drive as per normal but this time it stayed in first gear even though I had it in drive. While driving, I could manually shift it into second and it will go into second but it will not shift into 3rd gear when I shift it into Drive, what could be the problem? The OBD2 reader indicates a P1121 is causing the Service Engine light to co
Yes the problem is the throttle position sensor. you need a new one. it isn't shifting because the transmission isn't getting a signal from the tps. so it thinks your foot is all the way to the floor so it wont change into 3rd until it redlines. chan ... Ford E-150
1988 Ford F250, 5.8 liter, 4X4, automatic transmission. Problem: transmission -- 1st works fine, 2nd works fine, Drive stays in 1st and will not shift to 2nd or 3rd. If manually in 2nd and shift to drive, it downshifts to 1st and will not shift up. What could cause this?

The gear shift indicator light in the instrument cluster shows that the transmission is in 3rd gear at all times once the ignition switch is turned to the on/start position even when the transmission is actually in park or any other gear position. The transmission works as it should do when driving and shifts up and down the range as normal but the light on the cluster never moves from the 3rd gear position. I have changed the park/neutral switch but this did not fix the problem.

My 2003 gmc sierra 1500 2wd. transmission problem first the truck wouldnt move in drive but you could manualy shift from 1st 2nd 3rd then to drive and would be fine but if you stopped in drive it would not go unless you started over with 1st 2nd 3rd. two days like that and the truck wont move in any gear. i replaced fluid, filter, and did the lucas transmission treatment fluid with no luck. could it be a sending unit or solinoid?

1992 Dodge D150 2x4 Automatic 318ci/5.2L V8 Truck drives okay, but shifts hard from 1st-2nd-3rd. (Overdrive does NOT engage, but has worked in the past, since shifting issues started) Also, slowing from cruising speed of 65 mph, transmission will not down-shift until about 10 to 15 mph. At this point, vehicle shudders like a standard type transmission would do. I have heard multiple solutions from torque converter to 'tuning' transmission to solenoids. What do you think I should do?

My 2001 Elantra is not shifting right. Sometimes it work just fine. Other times it wants to shift hard from 2nd to 3rd. After that it remains in 3rd till I turn off engine. Even when I slow down or stop it stays in 3rd or Drive. At 55 mph it revs at 3000 rpm, should be 2000 rpm. My alternator is also squealing when I start up the car. Do you think the alternator is not providing enough power to let transmission shift correctly or do you think this is a speed sensor issue. Again sometimes car

I have a 2005 chevy avalanche 2 wheel drive, the other day I was driving through and intersection and out of nowhere it was like I was in neutral. There has never been any grinding noise, banging, clanking, or anything else that would have warned me of a transmission problem. Now, the truck will not take off in either drive or 3rd but if I put it in 2nd and get going I can manually shift it into 3rd or drive and it works perfect untill I slow down below appx. 15mph.

98 Mercury Mystique. The transmission shifts from 1st to 3rd and will not go into overdrive. This is the second transmission with exactly the same problem. I had a junkyard transmission put in the car 75 days ago. The newer transmission was working fine, shifting through all the gears till yesterday when this condition started while I was driving. There was no particular warning, although the car started stuttering several weeks ago. The stutter feels more like an engine problem and I don't thin

The transmission is not shifting properly. When starting from a stop I have to let off of the gas to allow it to up shift. At highway speed (55 -75mph) the transmission does not remain in 4th (over drive). It will shift freely into 4th but when I give it any gas - including gas to maintain the speed - it easily down shifts to 3rd.
Look for a vac hose leak, test the modulator. ... 2006 Chevrolet Silverado

I have a 1999 grand cherokee. The check engine light came on with a P1768 code. If I keep the trans in the "drive" position and start off, it feels like the transmission is in 3rd gear. No shifting occurs and will not shift to overdrive. I can manually change gears from 1st to 3rd normally, but still no overdrive. Is the problem with the shift solenoids or something else.

I have a 2001 V8 Lincoln LS and have tranny problems. The reverse does not work and the transmission will not shift automatically. If I put it in any gear on the auto side, I can hear it engage but when I hit the gas, it just revs. If I pull the shifter down to drive then over to the SST, it drives fine as long as I use SST to shift. Going from 2nd to 3rd it will pause a bit longer then shifting into other gears, but upshift and downshift, it seems to do fine. I would live with it as is, if I ha

Transmission shifts from 3rd to what seems like neutral while driving (engine revs, but no acceleration). Happens around 35-40 mph and shift fine from 1-2 and 2-3, but won't shift 3-4, always goes into this netural state. It's an Automatic Transaxle, 1.5L SOHC, and the transmission has always had rough downshifts but nothing to this extreme. Is this a sensor, since it always happens, or is it something bigger?

My 6 cyl automatic transmission stays in 2nd gear at all speeds. The car starts off slowly in 2nd gear and never gets into 3rd which use to drop the rpms down to the normal range. Also the overdrive indicator light stays on and will not go off when pushed. When I put the car in drive 1 the rpms go up and when I shift to drive 2 they don't drop down. The rpms do drop down when I move the lever to D (Drive). The rpms stay up and never shift down when I hit 50 t0 60 mph.
