Chevrolet - Avalanche :: Transmission Shifts A Little Hard Going From 1st To 2nd Gear
Nov 1, 2016
Have a 2002 avalanche Z71. Transmission was rebuilt 33k ago. It currently shifts a little hard going from 1 to 2nd. Real problem shows up between 40 mph and 50 mph. It suddenly shifts into overdrive which drops the engine rpm waaay down and starts lugging the engine.
Took it back to the guys who did the rebuild. They drove it around and noticed that the computer reported no codes. They claimed it was the TPS and said to replace it. I did. Problem is still there.
Took it to a highly trusted mechanic. They said they think the valve body needs replacing but they don't do transmissions. The guy they recommend drove it around and he thinks it is the torque converter.
I am wondering what causes the computer to decide when it is time to shift into overdrive and I am wondering if there is some sensor that has gone whacko and needs to be replaced instead of starting to tear the transmission apart.

I have a 1998 chevy blazer v6 about 127024 miles. My transmission shifts hard out of first gear when i get to 4 gear and it shifts hard. When car warms up really good car shifts find out of first gear but 4th gear still shifts hard. I did change transmission fluid and new filter in it and I check fluid level and it's full.

130,000 miles transmission shifts hard in every gear sometimes other times it is completely fine. Thought about servicing it with new fluid, filter, flush but have heard that this could cause problems since so many miles...

I have a 2003 Santa Fe 3.5l FWD 155k miles. Car has been incredibly trouble free until now. When the transmission up-shifts from 2nd to 3rd there is a hard jolt. All other up-shift and down-shift points work smooth. Occasionally will shift smooth just after I start the car or if I am accelerating hard. The rough shift happens whether I am in D or use the "manual" shift control. This coincidentally(?) started just about the time I had a battery die hard and an O2 sensor fail. Both have been replaced. Changed the AT fluid and no difference. No engine codes, but I think the AT codes don't show there? What might be going on? Any chance the battery failure had anything to do with this? Seems odd that battery, O2 sensor and transmission all start acting up at the same time.

My 1997 F250 Heavy duty shifts very hard and sometimes feel like it slips out of gear (i press the gas pedal to the floor and speedometer rises very slow and truck doesn't move like it should.

I currently have a 2006 F-250 6.0 with 187,XXX.
My problem that i am having is that the transmission recently within a couple weeks started acting weird about the same time 3 of my fuel injectors started failing. When i start up the truck and put it into drive it takes about 3-5 seconds to shift. Once it's in drive it runs pretty well but it will start shifting out of normal when i go to accelerate. Also when i go to slow down sometime the transmission shifts hard to a lower gear. I also have a video of the sound that it had started to make since its hard to describe.
Here are attached videos and photos. I want to hopefully fix the problems myself so i can learn more about my truck. I am going to handle the fuel injectors here soon since 2 are failing and ones about to these have been causing the truck to shudder at around 47-53 mph but after that its fine.
The transmission is stocked and never been altered, i do admit for 3-4 years I have changed the fluids or filters.
The truck is bullet proofed, sct tuner, upgraded turbo from stock, 4" exhaust, head studs and new everything when the engine was rebuilt and bulletproofed.
I plan on going to ford tmw to have them figure out the problem and hopefully its just solenoids so i can fix it myself. I have a link posted also where you can hear the noise it has been making when in R P and when shifting going down the road and it is a automatic.

2000 cavalier z24 2.4 170k automatic....
At first I thought this was a transmission fluid problem but had it checked and it's full. This may be a combo of 2 issues. At first it shifted so hard I couldn't really drive the car. AutoZone computer said the tp sensor needed replaced. I got the tp sensor and the issue did change for the better in that I can drive the car now but there is still a problem.
Its an automatic 2000 cavalier z24 2.4. shifts hard into drive and through the gears, although a bit softer into 3rd and 4th. The weird thing is, and this is how I manage driving it with less issue, is that if I slightly let off the gas real quick and push again when I think it should shift normally, it does. Every time. If I don't let off the gas and push again slightly it will shift late and hard which I imagine isn't good for the trans to deal with.
Not sure if it might be something like a speed sensor or what.

My 2002 Impala 3.4l sometimes starts shifting hard through all gears. It's not all the time. I have heard of others with this same problem and a transaxle service is apparently not the fix.

I have a 1993 4WD Toyota extended cab pickup with 200,000 miles on it that is getting hard to shift into first gear. I have to double/triple clutch run through the gears to get it to shift into first. It is not hard to shift all the time but the issue is getting more and more frequent.

I got my blazer look at and here what they come up with so far. Transmission fluid is discolored. Transmission shifts late between 3rd and 4th at 52 mph. Transmission slips between 2nd and 3rd gears at 32 mph. Lock up 41-43 mph in and out. I never told them this but I change the transmission fluid about a week before i took it there and when I check the fluid it was nice and clean and not burned like he said it was. He said most likely it internal damage.for them to take a look in side to see what is wrong with cost me 400.00 and I said no.

My 98 honda v6 accord shifts hard sometimes when going into and out of low gears. The transmission guy told me it had to do with the material that was on the clutches wearing off, dislodging, and clogging things. I have been driving the car for several years as is. Should I have the tranny rebuild or keep driving? Am I making matters worse by driving it as is?

I'm sure this has been brought up before. Whats the rattle you hear when accelerating hard when the transmission shifts? Exhaust note, exhaust hardware, dsg transmission, engine sound?

I just rebuilt my E4OD transmission in my 1996 F250 7.3L it has all new clutch packs torque converter and a shift kit. When I first put itback together it would not shift out of second cleaned mlps and shifts threw all the gears now. I took it out on the road to test it and this thing ran great shifted smooth and quick could not askfor any better but when Trans temp gets around 140-150deg it shifts hard and od light flashes. I have ordered a scanner to read the codes but won’t be in till later this week. What I could check in the meantime.

Got 2004 v10 and my truck shifts hard into 2nd gear when starting off slow. If I take off at a faster pace it does not do it.

i have a 2000 grand am with a 3400 engine and stock trans, i did a full engine swap in the car a few months ago for a friend and it was running fine, the engine and trans came out of an 04 grand am. I bought the car for a second vehicle for my every day driver after he changed the (tfp) sensor, and it shifts fine, but it is still showing a P1810 code, and shifts hard after driving it for a while but only when putting it in gear. What it can be?

Our intrepid 3.5L with 135000 miles has been acting up a bit. Its had a couple hard shifts over the last few days/week that almost seemed like an engine hesitation, and this morning when slowing down from highway speed into a small town, it abruptly shifted down to 2nd and stayed there like its in "limp mode" ??.
Pulled over and checked fluid. Level looked good and smelled ok but has a brown tinge to the pink fluid.
Started to go again and it still wouldn't shift. Pulled over and shut car off. Checked codes P700 and P138.
Started car up and it shifted fine for the next 28 miles. Shut car off and parked it.

A while ago, I acquired a 1991 Mazda 626 automatic (currently 105,000 miles) that now has what appear to be the beginning of transmission issues. It hard shifts from 1st to 2nd - the shift jerks really hard when the car is cold but once I've driven it for 15-20 minutes the hard shift almost disappears completely and stays that way as long as the car is warm - except for stop and go traffic (Seattle traffic) than the hard shift comes back no matter how long I've been driving. The only other shifting issue I notice is on the hills where it seems to shift more frequently than I might expect it too.
Other than what I've described this car is in perfect condition inside and out, as well as engine-wise. My question is on transmissions and whether I should get a rebuilt one. I've taken it to multiple transmission shops and almost all have told me two things 1) I need a new transmission and 2) that the issue is a hard component problem and I could most likely drive this car for months or years without having to replace the transmission - if I want to put up with the rough shifts. They recommended just driving it until the transmission goes out and then replacing it.

I have a 2003 Mazda 6. Almost every day, after starting it and driving maybe .10 of a mile, it seems as my car shifts, it shifts really hard, like a thump. I am thinking of having the Transmission serviced. Is this worth it? About what should the cost be? What do they do, just drain the fluid and add new?

2000 Ranger autimatic, 2.5 lt 2wd, 155,000 miles. To my knowledge it has never had a tranny flush or the fluid changed. I have noticed last week that when you are taking off from a stop sign it jerks going into gear. This only happens when you are taking off all the other shifts are smooth. The transmission fluid color is redish-brown and doesn't have a burnt odor. I don't know where to start. Do I get a tranny flush, change the fluid or is it something else?

I have 1993 F-350, 4X4, four door with a 460 fuelie and a 4EOD. That"s a bunch of 4's! I bought this pickup with 186,000 miles on it in 2005 or so, really just to haul fire wood and go to the dump once every 6 months. I don't know if the the tranny has ever been rebuilt. Nothing else on the pickup has been rebuilt. It now has 196,000 miles on it. In the past the tranny always shifted like a stock 4EOD. Kind of slides into the first three gears then into overdrive pretty solid. I took it out to go to the dump last week and it was just like always until it took it to taco party last night and it started to shift real abrupty. Doesn't matter how fast you go, it hits just as hard if you are on the gas or just casually cruising. It is hard in every gear. My first thought was that it may be low on fluid. When it is hot, idling in park after a drive I don't see oil in the little holes on the dip stick. I see oil on the dip stick but not in the little holes. Am I correct in thinking I should see oil in the holes? Actually I will see oil in the little holes when I first pull it out, then if i wipe it, put it back in, I see no oil in the holes. Engine idling in park of course.
