Downshift Slip With WOT

Hey guys just bought the comp g month or so ago and I already notice what seems to be a tranny issue. Tranny seems to slip and then kinda bang into gear with WOT at highway speeds. If I ease into the trottle the issue does not seem to be there...also it does do it once in awhile in town but for the most part seems to be at highway speeds. I am looking to do a trans flush and filter but looking to get a second opinion on this issue. Thanx
 


You mention it does it infrequently in town. Does this mean it'll slip into different gears, or is it just one gear that it seems to slip into?

Well I tried a couple diff downshifts on my way home and it deff seems to be downshifting from OD into 3rd...I will be cruising at 60mph and punch it to get around someone and it takes about 1.5 second to decide which gear to go into and then it slams into gear....I got it to downshift into 2nd and it downshifts completely normal....with the in town driving it will clunk into not sure which gear but I will normal be coasting under 25mph in rush hour traffic and then I give it gas to start moving fast and it will clunk into gear same way it slams into 3rd just not so violently...this is my first automatic car so maybe im just dumb but it seams like it goes into OD real soon
 
How are the fluids? Have you taken the vehicle into the dealer for this issue? If so, what was the outcome? Keep us posted.

A couple of weeks ago i hammered on my gtp and it bounced off the rev limiter before slamming into 1st and squealing tires then taking off like normal. I put in my zzp pcm in with the upped line pressure and such and it hasn't done it since.

Yeah I talked to a friend of mine and he said he should be able to tune this issue out with upped line pressure...till then I will prob just do a filter and fluid change...doesn't seem to be getting worse so I will just drive it easy until then

lol, by that customer assistance, do you mean "encourage people to go to the dealership for every little hiccup and check engine light."?

Im not sure what "normal" behavior is, only ever driven one GP but when Im gettin on the interstate and Im on the ramp goin about 35, I often like to hammer it and have some fun getting on.

When I do that it takes a second to shift, like it'll be at 1.5k rpm, and watching the tach after I hammer it, I lose power for just a second like it's in neutral, as I see the tach climb up to like 3k and then I feel the power kick in and I take off hard...

No slamming or anything though, it's all pretty smooth.

Except for high throttle applications, all my other shifts are pretty lightning quick and gentle

Yeah if im getting on the freeway it acts fine...all downshifts are normal except when it downshifts from OD into 3rd when I have the hammer down...if I ease into it with downshift into third normal then I toss the hammer down...ill keep everyone posted after the fluid and filter change

This is exactly what mine does. Understand this is an old thread, but did you ever fix this and how
