remmans Posted February 14, 2005 Report Share Posted February 14, 2005 I have the 4t80e transmission in a 1995 Aurora. I just put a motor and tranny back in the car. I had bought the car from a lady with a cracked block (froze) so I had to replace the motor. She had also told me that it would not shift into 3rd gear because somebody that tried to steal the car did something to it. When she took it to a transmission shop they told her it was the shifter cable? When I had the transmission out I replaced the shift solenoids, speed sensor and the TCC. When flooring the gas on the car the car shifts at 6000 no problem. When I am driving it normal the shift normal sometimes with no check engine light. When I take off from a stop sign the next time it will not really shift from 2 to 3rd unless I accelerate then let off the gas then when hit the gas again it will down shift again into 2nd gear and the check engine light will come on. The light will come on then go off depending if the tranny is working or not. Any ideas? I heard maybe modulator? Anybody know where that is located? Thanks in advance for any help you might be able to provide? Link to comment Share on other sites More sharing options...
