Need some help brainstorming a problem im having with my transmission it will not shift into overdrive. Could it be the trans is going bad or something simple to fix? any input is appreciated

 

yes, is it shifting 4 times? have you tried reseting the tv cable. SUBJECT: 700R4 Throttle Valve Cable Adjustments

 

No it only shifts three times. almost got it up to 80 and still would not shift into final gear. I have tried to adjust the cable but really did not know how. It shifts really hard into second and kinda hard into third and then nothing. I have changed the trans once and had it out of the car atleast two more times was not a problem untill recently, all started when the radiator blew

 

make sure your shift cable is adjusted right to Adjust A4 Trans Linkage

 

That's right, a 4 speed automatic only shifts 3 times, NOT 4: 1-2, 2-3, 3-4 = 3 shifts. You may or may not "feel" the t.c. lock up (that's not a shift), and the rpm's will drop by maybe a couple hundred.

 

forgot n to 1st

 

No I didn't. That's a gear change, not a "shift".

 

lol im not retarded I know all this. maybe i should have said it only shifts twice.... but in any case as i said before it wont shift into fourth. No rpm change at all. at 65 the rpms are around a little over 2500 which is too high its eating threw gas and to add to that it wont shift out of first again. Have not had the chance to adjust anything yet to see if it helps but like i said any input is appreciated. also when i say wont shift out of first i mean it wont shift at all.... like even if i shift it manually it stays in first.

 

That's good to know, we'll make a note of that for the future. lol
Questions like "why can't I feel my 4 speed auto shift 4 times" don't surprise me though. It's a logical thing to get out of the way.
So, are you saying instead of shifting 1-2-3 (no 4th) as before, it's now not coming out of first?

 

check and make sure the tv cable is not unhooked or broken. mine did weird stuff like that when it was not hooked up right
