gearing or tune?

[4drcbra]

I have a 4.10 gear and a custom tune. During WOT at about 100mph car shifts and falls on its face. Tune need adjusted or just by product of gear?

Where is the speed limiter set in the tune?

[guspech750]

For sure not a product of my 4.10's.

Removed limiter. I realized i activated OD and it was shifting into OD at high rpm/speed. I didnt back off at 6000 then let it shift into OD first. Prob should make sure im not WOT in OD to keep trans in one piece

[4drcbra]

Well, i tried backing off, activating OD, letting it shift and gettin back in it. After the shift just falls flat o. Its face. Any ideas?

[justbob]

Sounds as if the T/C is locking the second OD kicks in. What's the RPM's doing?

[martyo]

When you say it falls on its face, do you mean it is not going opast 100 or just accelerating at a slower rate?

[4drcbra]

Rpm is about 6000 at shift and then drops to.4000 and acceleration just falls off like i deployed a chute.

Go back to who tuned it and tell them they suck. Then go to alt auto and get new tune

[4drcbra]

taking it back to shop probably Saturday or sometime next week. Gonna take a peak at the tune and make a few adjustments. I think it may be a mistake or something because the other marauders that have been tuned do not have this issue

[camelgrundle]

Yeah. If u have a handheld device try putting it back to stock then re installing it. If not do what u said. I know mine did not take correctly first time for some reason.
