It might fix the problem but you may also have a shift sensor that is starting to go bad as well take you suburban to autozone or an o'reillys if you have one of those auto parts stores near you and they can do a scan on all the sensors to tell you if your vehicle is showing any problems with any of your sensors I hope this helps you out.

SOURCE: 4l60e slips in 3rd and 4th

There are to many things that can cause this problem, best thing to is go get the ECM scanned for DTC codes at a transmission shop or Auto zone or Parts Source since they scan for free.
The ECM should have DTC code in it's memory on how the transmission is Performing and have the Transmission line tested for Fluid pressure.
Good luck and hope this helps. Oh and also ways check with more then on transmission shop if there tell you that you need a new Transmission,
It could be a simple as the transmission filter falling off causing the lost of transmission fluid pressure. Check the transmission fluid too.

SOURCE: 1994 silverado 4L60E transmission not wanting to shift corrrect

If you have not worked on a 4L50E transmission before, leave it to someone who is familiar with the the 4L60E. The solenoid is in the valve body and i know some who have put things back together and needed to take it apart again over something simple as a servo pin in revers. Best thing to do is get the truck scanned at Auto Zone free of charge or at a transmission shop with a tech 2 scanner for DTC codes. If there is a bad throttle body sensor or it's misaligned, it would affect your transmission's performance. The throttle body sensor send's signals to the ECM which calculates the amount of transmission fluid pressure though out the shift points, if that signal is bad then your shift points and firmness will be affected. There is also a cheap and great performance upgrade for around $50.00. You have a Transmission shop swap out the servo's for a Corvette servo's, it can be done in 30 min with out taking the transmission down or removing the transmission oil pan off.
Recap, have the transmission fluid and oil changed and have the throttle body sensor tested. It should show a smooth gradual increase in resistance with out any fluctuation. You truck is 15 years old and it may have a dead spot on the sensor now and it may need to be replaced. Good luck and keep me posted, Be glad to help and you can also have the transmission shop do a transmission pressure line test.

SOURCE: wont shift into 2nd gear revs high until it finally goes into 3rd

If there is a Auto Zone around your area, have the blazer scanned for any DTC codes that is related to the transmission issues. It could be a fault sensor, bad wires, or bad solenoid in the valve body. The scan should help indicate if there is an electrical issues or it's going to be mechanical. You can try adding a transmission additive to flush out the system and then replace the transmission filter and oil. Make sure you flush out all the transmission oil, it could be as simple as the 2nd and 4th solenoids are seized with dirt and not activating. Good luck and keep me posted. The solenoid is in the valve body and is not that expansive for the parts, you just have to find a good transmission shop that will fix this simple problem and not try to get you to put in a new transmission.

SOURCE: 4l60e going from 1st to 3rd and dont have overdrive any more

You most likely have a broken sunshell inside the transmission. They tend to go out when the transmission is shifted to drive when while still rolling in reverse.

My 2001 GMC Jimmy 4x4 Automatic with 84K miles. It winds when I put it in reverse and I think I only have 1st and 2nd gear. Additionally it revs high, like over 3000 rpm, delays and then eventually...


It winds up in 1st and then shifts right from 1st into 3rd. Then never shifts into 4th. Plus rev is gone. You broke the sun shell. The transmission will need to rebuilt or replaced.
