Hello all, sometines when im passing and the tranny goes in overdrive, it works fine, but when it goes to shift in high gear again, its almost like the thing goes in neutral. I can push on the gas and the engine just reves up. Afew minutes later it goes back to normal. Its been like it now for quite some time. My fluid has always been changed regularly. Could this be torque converter related? Oh yeah, its a '98 4.6L, not sure whish transmission. thanks
