Wierd 4l60e problem
Ive got a 99 trans am with the 4l60e, it has started to act up in 3rd and overdrive, in third the transmission seems to have a very bad vibration, overdrive just wants to slip. transmission only had 40k miles. The vibration is interminute it only seems to do it every once in a while. Any ideas whats going wrong?

I would have to say that the slipping in forth is the band not the 3-4 clutch. However the vibration sounds like a tcc issue. If you lightly apply the break pedal while in third, keeping constant pressure on the gas pedal, does the vibration go away? This will tell you that you have a tcc issue. Vince

I said 3-4 clutch because he said it vibrates i 3rd and he made no reference to 2nd having any problem at all so I would guess 3-4 clutch is going bad hence vibration slip in third and since more strain slipping in fourth through the 3-4 frictions , but either are possible,And the lockup check in a good idea but i would say as before either way you will be going into it or replacing the unit based on the information you supplied.
