i just pulled my car our for summer and it wont shift from frist to second unless i take the car up to 3500 rpm and let it sit there for about a second. My frist gear is very strong and when i do get it into second it feels fine. At wot it will not shift ether. i adj. the tv cable the way i read on here how to do it and that did not help.... any help would be great!! thanks guys

 

Could be that the TV valve (in the valve body) is stuck.
The MTV Up valve (in the valve body) is also an option.

Start the car and snap the TV cable, at the throttle body, a few times. Just pull it and let it "snap" back. Sometimes this will flood the TV circuit and cause a stuck TV valve to free up.

ok i did that and it seemed to help a little could u please explain real fast how to SET the tv cable i know u push in the little button and then u push the plunger thing all the way in but then when u snap the throttle open do u hold the button down again or not? thanks

 

Push the cable back toward the firewall, then push the gas pedal to the floor (without pushing in on the lock button). The cable should "ratchet" out to where it's pretty close. You want your shift points to be at 15-18 MPH for the 1-2 and 35-38 for the 2-3 (under normal throttle). Moving the cable toward the firewall will increase pressure, making the shifts later and firmer. The other direction will do the opposite.

Thank you very much!!! it shifts now!!! but one more thing, when i push it all the way in it wont rachet out.. the only way it will set back out is if i hold the button and snap the throttle forward.....??

 

nevermind, i took it out the next day and it didnt shift again back to square one.........

 

I was going to suggest that it could be the shift solenoids inside the tranny, but not sure about your tranny. Mine was a 4L60E and acted the same way...My solenoids were shot. Replaced them and everything was fine.

Frank can tell you alot more than I though.

 

This sounds like a valve trying to hang up...Most likely the TV valve.

So is there anything i can do to fix this?? i have a lift at my house. so i can pull the tranny or do whatever. should i pull the valve body out?

 

i went back out to my shop after work and i pulled on the tv cable again many times like u said to do befor. Then i took the car back out and it shifted again. So why is the throttle valve sticking?? what can i do to fix it for good? i dont want to open the hood and pull on the cable every time i go out to drive my car... thank you guys so much for any of your help
