When do trannies start having 2nd gear shift problems?

Usually when those trannies start having 2nd gear shift problems it time for a rebuild. There were a ton of updates to the valve body in those that pertain to hard/late 2nd gear shifts. Have it scanned first, get back to us and we can go from there.

Why does my car not shift into 2nd gear?

Acceleration is virtually zero. After stopping the car (say at a redlight), starting again it will refuse to shift into 2nd gear. When it finally does, it will make a hard “thunk” sound and the car will surge forward. If the car is stopped and turned off for awhile, everything seems to go back to normal.

What should I do if my 4L60E is shifting hard?

Why is my GM truck transmission not shifting?

Your issue is a common one with the transmission in that truck (and many other GM’s that use the same 4L60E transmission). It is caused by the worn rings and hardened seals on the interior parts like the front pump and pressure control solenoid.

What causes a Chevy transmission to not shift?

Low transmission fluid level. Chevy transmission won’t shift, stuck in 1st gear or limp mode – Speedometer may also display zero at all times. It could be internal transmission failure, low transmission fluid, or faulty Vehicle Speed Sensor (VSS sensor).

Is there a problem shifting from 2nd to 3rd gear?

Have check engine, the computer says it needs the shift solenoid, the problem is it will not shift from 2nd to 3rd gear on an automatic transmission. Also found a vacuum line near to transmission disconnected but not sure where it goes.

What should I do if my transmission shifts hard?

Clean or change this spring and put all the components back together to reassemble the transmission. If you have not changed the fluid and replaced the filter already, do that while changing these parts. Otherwise, just keep the filter in a bag while changing the o-ring or spring and then re-install it.

Why does my transmission shift hard after replacing the fuel filter?

Even experienced mechanics struggle to find out the exact reasons for this problem. The shifting hard problem can persist even after replacing the fuel filter and pressure control solenoids. Sometimes, it happens when the engine is cold and you try to kick it off right away without warming up first.

Why is my Blazer still picking up speed?

2) The Blazer still picks up speed and drives well except for the rubbing/vibration now. Would having pulled out and put back in the dash switches or being in such close proximity to the TCCM caused issues?

What happens when an automatic transmission shifts hard?

An automatic transmission is hydraulically controlled and designed to shift smoothly. When the transmission shifts hard, it can damage internal components including valve bodies, hydraulic lines, and in some cases mechanical gears.

Can a bad speed sensor affect shift timing?

Harsh or improper shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing,…

Why does my front differential not work in 4×4?

I’m not sure if it’s easy to do with an automatic transmission, but the front differential doesn’t seem to like it when you attempt to go into 4×4 when the front tires are not spinning (or close to it) and the rears are- usually with the RPMs above idle.
