okay i rebuildt my tahoe transmission after the 3-4 clutch material finally worn out
what causes the is the 3-4 apply pistion seal wears out and slowly there is less and less pressure to hold 3rd and 4th gear
what will happen is youll itll start to kick outta 4th going to down the freeway randomely and eventually more frequent till itll try to shift to 4th but it wont hold itll just rev up and backto 3rd very soon 3rd will act the same way then it wont be there
you mite as well just prepare for sticker shock and bite the bullet and rebuild it there is no temporary bandaids or fixes changing out fluid like i did it will get worse faster
cuz all the abrasive clutch material is floating around in the tranny fluid and thats whats holding her together when you flushall that out eventually itll be like you got a 2 speed tranny

151k im sure u know what is happening .... more than likely the clutches are worn and just not engaging completely. yes a trans kit and upping the line pressure will make it shift better but this is only a temporary fix. you are more than likely on your way to a rebuild

My 2005 Yukon is at 176k and drives fine but slips when a trailer is on the back and has a whining noise when in the higher RPM so it's time for a rebuild for me as well but babying it for now until I decide which shop to get it done at
