Silverado :: 98 Chevy Truck With 4L60E Has No Second Gear - Shift From 1st Into 3rd


Mar 24, 2013

I have a 98 Chevy truck with a 4L60E. It has no second gear. I was sitting in park for about 10 minutes with the engine running, then put it in drive and it never shifted into second. It felt like it went straight to 3rd. I played with it manually until I figured out I had reverse, 1st, 3rd, 4th and torque converter lockup, just no second gear. My acceleration rate was medium and when I reach about 27-28 mph it would shift from 1st into 3rd. It has 230K on it so I rebuilt it with all the typical parts - frictions, steels, band, sun shell etc., still no second. I then pulled the pan back off and replaced the spacer plate and put in a shift kit. While I had it down I put a corvette servo in and did an air check. It worked fine. I could feel the band tighten.

Both the 1-2 and 2-3 solenoids checked good at 23 ohms. I swapped their positions to see if it would make a difference. I also checked to make sure the 1-2 accumulator piston wasn't stuck in its bore, the spring was new from the shift kit. It was fine. Put it back together...still no second gear. When I originally pulled the pan off for the rebuild, the pan was free of any debris and was very clean. I then drove it a couple of miles to a local transmission shop. They put their scan tool on it and drove it around the block. There were no codes and the ECM was calling for second gear. It doesn't sound mechanical since almost all the parts have been replaced, rebuilt or inspected that affect the 1-2 shift. It sounds electrical. Is there anything I have missed?

Silverado :: 1997 4L60E Transmission - Truck Will Not Shift Into 2nd Gear While Driving

97 Silverado - 5.7 with 4l60e trans. truck will not shift into 2nd gear while driving. stays in first gear until rpm are high and shifts into 3rd. under hard acceleration will stay in 1st until let off gas then shift into 3rd. manual shifting results in same, no 2nd gear until selector is moved into 3rd then shifts into 3rd. Haven't got any trans codes, fluid change netted no change in performance, fluid was pretty dirty but didn't smell burned, and there were no metal shavings in pan.

Chevy - Silverado :: 1996 Won't Shift Into High Gear

My dad's 1996 Chevy Silverado will not shift into hi gear. The truck starts up fine and he can drive it but for some reason it won't shift into hi gear. Him and I are clueless as to why it won't. He has a 1996 Chevy Silverado, 6.5 liter V-8 automatic transmission, and its a diesel. We really want to fix the truck ourselves so we are trying to avoid taking it to a shop.

C/K :: 1994 - 4l60E Loses 1st Gear - Won't Shift Automatically When Hot

I have a 1994 C-1500 4.3L with a 4L60E transmission. After driving for 30-40 minutes it loses 1st gear and you have to manually shift between gears. R, 2, D and OD can be manually selected but there is no automatic up or down shifting. There isn't any gear slipping prior to this. After sitting for 25-30 minutes everything works fine. I have noticed that sometimes before the problem occurs that if i manually select 1st gear it will stay in 1st & sometimes it will automatically shift to 2nd even though the gear selector is in 1st. Also it usually shifts into D at about 30 mph but sometimes it stays in 2nd until I manually shift down to 2nd and back up to D. It isn't giving any relevant codes (use jumper & flash codes). I'm thinking possibly faulty solenoid(s), but not sure.

Silverado :: 98 5.7 Chevy Truck Not Starting

I have a 98 chevy truck that won't start. After it sits. It was starting after cycling the key a few times. But now it won't start. Could it be the pump? I hear it running.

Or could it be the regulator? It was running good after it started. No check engine light, no gas smell, and no rough idle.

Silverado :: 1993 Chevy 2WD - When Accelerating RPMs Go Way Up And Won't Shift

I have a 1993 Chevy Silverado, 350, 2WD. It has a 4L60E transmission. I just started having a problem shifting from 1st to 2nd. When accelerating the RPM's go way up and won't shift until I let off the throttle. Then it shifts into all other gears normally.

If I accelerate slowly. it will shift into 2nd at about 16 MPH. It will then shift into all other gears normally. I have replaced the Throttle Position Sensor, flushed the transmission and replaced the filter and fluid. This made know change in performance.

I am now suspecting that it might be the 1-2 shift solenoid. The check engine light is not on and everything else works fine.

Silverado :: 2000 Chevy Truck Won't Start - Security Light On

I have a 2000 Chevy silverado. I recently was having problems with the transmittion not switching correctly. Long story short the shop told me to fix the problem I had to put in

A new transmition as well as a new computer which I did, from another Chevy. It worked for a few days then The truck was not starting and had security light on. Had alarm specialist take look and he said the computer had to be reprogrammed. It was reprogrammed at merles. And was still not working. Its unable to start, starts at random once in a long while. ignition switch was changed and still gave same problem. Took to another shop they had a specialist take a look and he said the computer had to be reprogrammed again.

Also would it be possible to bypass the anti theft system by adding a remote start, or cutting some wires. I just really need to get this truck running.

Silverado :: 88 Chevy K1500 - Truck Lacks Power / It Idles Rough

I have an 88 chevy K-1500 4x4 5.7L ... My truck lacks serious power, it idles rough, sometimes wont idle at all, sometimes Truck Idles fine. I have adjusted the timing to tdc, and 4 deg. both ways still runs like crap.. Sometimes I can keep it idleing, put it in rev. or drive, and it will die. I have no power and if I put my foot in it too much it will backfire. but will only backfires when in gear and press on the gas to put a load on the motor. I have replaced the: tps, map, egr, pcv, distributor, cap, ignition coil, rotor, plugs, wires, timing chain, both sprockets cam and crank, checked all hoses for leaks, replaced the injectors, the O2 sensor and have changed the intake gaskets. And am still having no luck...... I am bout to just drop an M80 in the gas tank and watch her burn..

Silverado :: 2006 Chevy Truck Hard Shifting Manual Transmission

2006 chevy 4.3 v6 5 speed manual trans. Very hard to shift into and out of gear , the truck has about 80,000 miles on it , its had the new trans fluid gm replaced for smoother shifting. If you hold the clutch pedal down on the floor hard it works fine. It all most like the pedal it screwed up. The pedal ass is plastic junk, I am thinking the pedal is bended. The clutch does not slip and I tried bleeding the clutch master cylinder and there are no leaks anywhere !

Silverado :: 2001 Chevy - Transmission Will Wind Out In 1st Gear And Not Shifting

I have a 2001 Chevy half ton 4wd. It has the 5.3L, 4L60E transmission, and a 246 transfer. I am having problems with shifting. if I out the truck in drive, the trans will wind out in 1st gear and not shift. I then pull it down to 2nd and it will shift. When it comes time for third gear, it will not shift at all. It just simply revs until it catches up with the speed at which the truck is rolling. I thought it was a bad tranny as I smoked one and replaced it with a used one so we rebuilt the tranny and it still does the exact same thing. Also the speedo is not working but the odometer is on. Don't know if its registering anything but its on. I have also checked every single fuse and maxi fuse in the engine compartment and the drivers side panel.

Silverado :: 2003 4L60e Trans Slips When Upshift 2nd To 3rd?

Truck has 222000 miles on it. With gentle acceleration not noticeable, with maybe half throttle rpms increase for say one second or two and then shifts smoothly into third, However at full throttle with the shift coming at 55 mph or so, it shifts perfectly with no slip. It also acts the same manually. I had asked my mechanic about changing the fluid and if it could fix the problem, he said, "well it could work or hurt it." After thinking about it, we decided to change the fluid. He did a full flush and cleaned out the pan which had lots of sludge in it but no pieces of metal in it that would seem to indicate a major internal problem. It doesn't seem to have made it much worse if at all, but did not fix it.

Cavalier :: 2001 Chevy Will Not Shift Into 1st / 3rd Or 5th Gear

I have a 2001 chevy cavalier, the base 2.2 model with a 5 speed manual transmission.

I can't shift into 1st, 3rd, or 5th gear. On occasion I can get into 1st but it pops out almost instantly. I have the shift boot up, it looks like the shifter won't go far enough to click into gear for the top 3 gears.

2nd and 4th don't have any issues, reverse works as well though can sometimes be more difficult than usual.

Chevy - Malibu :: 2011 Will Not Shift Out Of First Gear Into Reverse - CEL Came On

I have a 2011 Chevy Malibu, with a little over 100k miles on it. A couple weeks ago it started acting a little funny when I would shift into reverse after starting it after sitting for a while. I thought it might have been due to temperature as it didn't do it after the car had warmed up or when it was warmer out.

Yesterday it started acting up really bad, will not shift out of first gear, and will not shift into reverse, and the check engine light came on. I was able to get it up to O'Reilly's to get the codes. It came back with 2 separate codes.

P0700 - Transmission Control Module (TCM) Requested MIL IlluminationP0776 - Clutch Pressure Control (PC) Solenoid - Stuck Off

The guy there seemed to think that the second code was probably caused by the first one, and most likely the TCM needs replaced. It makes sense to me, but before I head down this path I want to get some input, as it is a little over $300 for the part.

Suburban :: 4L60E, Transmission Misses The Shift

[URL].....................

If I accelerate gently and keep the rpm down to about 2500 or less, I get a normal shift from 2 to 3 and I can then accelerate with vigor without any apparent problem.

If I accelerate the way I normally drive, at the 2 to 3 shift point the transmission misses the shift and I have to let off the throttle for a few seconds and wait for 3rd to engage. I usually see no codes, but once in a while P0758 reappears.

Both solenoids A and B have been replaced, as described in the thread referenced above.

More symptoms, and maybe this is a vital clue: the 3 to 4 shift is fine, but I've noticed that lockup takes a while to occur. When locked up, I normally see almost exactly 2000 rpm at 70 mph. I am seeing about 2150 rpm at 70 mph until lockup finally takes place, but I can't say exactly when it does happen---I have to watch the road now and again.

I understand there are a 3-2 solenoid and a pressure control solenoid, but I don't know enough about their purposes to decide that either needs to be replaced.

Malibu - Chevrolet - Transmissions :: 2007 Chevy Will Not Shift Into 2nd Gear When Start Driving

I have a 2007 Chevy Malibu with around 190000 miles on it. Recently, first thing in the morning then I start driving, that car will not shift into 2nd gear for a bit. The engine will rev up the 2000 RPM and stay there. After a while it will finally shift. The fact that the engine stays revved that high for that long makes me nervous.

Silverado :: 1991 V6 - While Driving Truck Seemed To Slip Out Of Gear And Not Go Back In

I drive a 91 Silverado, v6, standard transmission.

While I was driving my truck seemed to slip out of gear and wouldn't go back in. About 10 seconds later it shut off. I was able to ride the momentum and pull over. It tries to start when I'm turning the key, but nothing. I've ruled out the distributor and the battery. All I can think now is: transmission ....

I've had problems with my distributor rotor from time to time, but no real indication that my transmission was having troubles.

Silverado :: 2001 2500HD 8.1L Engine Idling When Truck Is In Gear

I have a 2001 2500HD P/U with the 8.1L V8. I have owned the truck for ~5yrs and used it with everything towing. For about the last three years, I have noticed that when the truck is in gear (Either Rev. or Drive) the engine idle almost acts like it is missing. It doesn't do this at higher RPM's (say over 1K) while driving.

Last spring I did a tune up (Plugs and wires) and a few of the plugs had quite a bit of build up so I figured that was what was causing the issue. For about 1wk after the tune up it seemed to clear things up (at least I didn't notice it), but then resurfaced.

My question is: should the "Coil" parts that feed each spark plug need replacing, or could they cause this symptom? The ignition system on this truck is a bit different that what I am used to seeing, so I am not sure where I should start looking for the problem.

Also, there are no error codes being thrown.
