hi i have a 87' firebird v6 with a auto tranny.
thing is i have to wait till my car is spinning 4000 rpms before it will switch to second gear
and to get to third i have to wait till i get to 50 miles per hour and after that i try to go faster and faster for it to switch to 4th but it doesnt switch after 3rd...
i looked up the TV cable thing but i dnt kno how to do it, it confuses me and doesnt make sence to me
plz help me with this problem i knt kno if its the tv cable or something else plz help my gas mileage is horrible!!!

 

Change the fluid and filter. I had the same problem, it ended up being some gunk stuck in the valves.

 

i did do a tranny fluid chane at jiffy lube and i have a leak in the tranny so i have to constantyle put tranny fluid so i still have this problem

 

Try shifting it manually till you fix it.

 

i just tried that shifting through each gear and still nothing shifts the same as if it was meant to be shifting that way

PLZ help this is really killing my gas mileage and this just happened a few days ago, it was working fine and now this is happeneing

 

What was going on when it started happening? sounds like a tv cable adjusted wrong. did it happen when "JIFFY LUBE" changed the tranny fluid? if so they prolly tried to re-adjust it "as a favor to the customer" to make you think they did something special and messed it up.

 

no this happened way after jiffy lube changed it and thisjust happened when i was on my way to work it it wouldnt switch out of first till i put oil in the tranny and then it was all messed up after it just switch late and there is no more over drive no mater how fast i go

 

you likely have a sticking THROTTLE VALVE in the valve body its a common problem with the 700r4. Likely the fluid and filter change loosened up some debris and it got in there, Its the risk of servicing a high mileage that hasn't been kept serviced. And no its not the service centers fault its just a risk like I said of doing a service.

 

so i gotta do a tranny change and check everything in it ?

 

Well you at least have to pull the valve body and see if the throttle valve is stuck

 

ok imsorry but im a little new to this where is the valve body? and wat do i do just move it around and see if its stuck.?

 

you might want to try your TV cable first befor you go diving into the valve body. if the TV cable moves freely then most likely your throttle valve is stuck. Jiffy Lube probably used BG trans cleaner and it churned up all the sediment and the Throttle valve ran over the sediment and stuck. if you want to do it yourself there are some good videos on you tube.

this is a link for removing the valve body on a 4L60E which is just an electronic 700r4. just ignore all the electronic stuff.

no i dont think jiffy lube has anything to do with it.

i took it there months ago.

the thing that happened was that i had a tranny leak and i ran out of tranny fluid and the way i noticed was when one day i took my car out and it wouldnt shift out of 1st till i put tranny fluid and then it didnt shift normally n e more

and to this day my car shifts out of first till i reach 30 and out of second when i reach 50 and no O/D its killing my mpg

i also checked my TV cable and it all seems to be tight i really dont know what the problem is please help someone!!!

 

Most likely trash has gotten in your THROTTLE VALVE and caused it to stick. Unfortunately while you could pull the valve body and clean and unstuck it more than likely this is and indication of another problem failure in progress, Your likely going to need a trans very soon
