Hello everyone
I own a 1995 Blazers with 110 k miles, my problem with the transmission, when the car is cold the transmission works well and there is no problem, but when it reaches the temperature in the engine to 190 f starts persistence on the second gear and does not change to the third gear and never when i press the pedal down to the floor ,its downshift to first gear and returned directly to the second gear. Even when i stop completely and try to start move trans remains on the second gear and not go back to the first gear .

thanks to all forum members and Visitors ans Special thanks to the Interested
note :no blowing fuses
new 3-2 control solenoid
torque converter pwm solenoid
filter and oil
torque converter

 

Will it go into 1st gear when manually pulled down into 1st?

What made you change the 3-2 downshift solenoid?

 

thanks for replying
well yes it go in ist gear when i shift manually
and about the solenoid i think its an original brand

 

i changed the 3-2 downshift solenoid because the scanner told me thats problem in it , its broken

any Idea ?????


well , about the codes i didn't know it because the man who scanned my car with the scanner told me that bad signal from 2-3 solenoid and when i opened it i find it broken .
i toke my car to a trans mechanical he tested it and told to me ( your trans is very good and nothing wrong in it ,try to add an external oil cooler ) he scanned it again and no codes at all
by the way ,two trans mechanical told me the same things( no problems in your trans and no codes)
thanks.

 

What were the specific codes that led you to replace the 3-2 solenoid? What testing was done to confirm that the 3-2 solenoid was actually faulty?

If you do not have any other codes currently, it may be worthwhile taking it to an experienced 4L60E mechanic and having the line pressures read along with hooking it up to a full feature, bi-directional scan tool capable of running the necessary tests.
