E4od torque converter issue? not shifting.....

Here is the deal, it's not happening all the time but it's often enough to be a real problem.

When i'm pulling off from a stop my engine will over rev before shifting into 2nd and some times i have to get off the throttle and then reapply. Almost like shifting gears with a standard.

Is this my torque converter, and what are my options for fixing this?

I currently have to drive like a granny in order to hit all my shift points properly. which really stinks cause i normally like to drive it like i stole it.

Any thoughts on this issue?

One more thing, I've got no flashing OD light and I have no codes showing up.

The shifting issue has progressively increased in frequency and duration.

My wife drove the truck the other day and kept on the gas all the way through the 2nd gear shifting issue. she said it banged pretty hard when the tranny finally shifted.

My sig has all my mods, i don't have chips, tunes, programs, or any other mods that aren't listed in the sig.

Whens the last time you changed the filter or had a flush?

Valve body is what changes the gears. Well, the solenoid tells the valve body when to change gears. Either the solenoid isn't telling the VB to shift, or the VB is not shifting when it should be. If the converter isn't slipping, then I'd lean towards VB issue.

Ahh kind of... PCM tells trans when to shift based on pressures measured by the shift solenoids in the valve bodies, there are 2... Start by draining fluid and changing filter, disconnect cooler lines and drain and flush cooler.

Its a pressure problem, most likely the accumulator valve, which is what is giving you the slamming.

If it persists after changing the filter and fluid, you can try flushing the trans itself. Most reputable trans shops can do this for you...
