I have a 04 Chevy Tahoe that Iam having. Transmission problems the trans goes frist and 2 gear then nothing I hooked it up to a scanner and it saids Iam going into 3 and 4 gear but it doesn’t feel like I am I chenge the solenoids a and b and converter solenoid chain speed sensors all of them is my trans shot

 

If it feels like neutral on the 2-3 shift the 3-4 clutch set is fried time for a rebuild or replacement

 

Did ya even Lower the Oil-Pan to see if your Transmission Fluid is Blackened and full of Debris?




= 4L60E No More Happy No More... Long Long Time No More Happy No More... Super Mega Long Time No More Super Mega Happy No More!!!

 

As said, I would lower the pan just to be sure, but most likely it is time from a rebuild.
