At WOT 1-2 shift fine but it dosent shift into 3rd on my 2000 ta with a 4le60. Someone told me it might be my transGo shift kit doing this dose any one got some insight

 

Not likley the transgo but most likley the 3-4 clutch set is going

 

Does it have reverse?

 

Third/reverse

 

I had a brain fart.....I was thinking about the sun shell, but hell thats only gonna effect 2nd and 4th.

 

I understand it happens to the best of us at least you know what a brain fart is lol

 

LOL and also reverse with a bad shell. JFWY But never the less it sounds as the 3-4 clutch is going out. Vince

 

Well i have about 20000 on that tranny and it was rebuilt it also surges in 2-3 shifts around 45mph if im not in it and in 3-4 shift around 55mph if im not in it.

 

Well again if the 1-2 shift feels good then I would have to say there is a 3-4 clutch issue

 

im having a very similar problem, during wot I will have it in D and go WOT and when it comes to shift into third it wont really and i have to let off the gas to get it to otherwise it will go into the red and bounce off the rev limiter. im not sure if its the tune b/c it never did this until i got it tuned so maybe the shift points arent set right there.

 

In your case that is possible though I still think original poster has a 3-4 clutch issue , You also have to anticipate comand to actual shift lag time when setting shift points particularly with the 2-3 shift since theres alot going on during that shift , fluild is being directed to the back side of servo for band release , and in the 3 0r d3 position fluild is also being directed to the overun clutch compounding this add in a little excessive clutch clearance and it can be 200 to I have seen people say as much as 800 rpm between command and actual shift

 

could that explain why it gets a hard chatter before it shifts gears

 

ttttt

 

slipping can sometimes feel like a rough chatter
