Newbie looking for a lil help with trans tables

[98tadriver]

Do these tables look ok to you all? my friend actually tuned my car a while back after we changed out the 2.73 rear for 3.42's. everything is great except one issue when im at the dragstrip- takes off like a raped ape, 1-2 shift is fine. then the car pulls hard thru 2nd gear but bangs the limiter and wont upshift into 3rd @ WOT. If im driving at 50mph on the street and go WOT, itll downshift into 2nd and upshift into 3rd just fine. i thought it was a bit odd. my tuner friend is really busy and I want to learn some stuff. any and all help is appreciated!

Drop the shift mph from 75 down to 70 in wot tables and try that. Here is a link to a guide you may find usefull.

I would ignore the Cruise, Hot Table and performance on your vehicle. Cruise is used while Cruise Control is engaged, Hot is used when there is a Over Temp condition and Performance is used on trucks with a Tow/Haul button.

What are the WOT Shift RPM's set to? Try making the 2-3 shift in WOT Shift Speed table 69 Mph which will match it to what the Normal table 2-3 at 100% tps.

thanks for the help guys. I appreciate it. This will definately help me understand some more things.

i believe the wot shift rpms are-

1-2 6000
2-3 5700
3-4 6000

now i just need to wait for some good weather to test out the fix

How come only 5700 through the 2-3 shift?

that's what my tuner had it set to. Once I can get traction from a 1st gear dig or roll, I'll be able to see if changing the WOT shift mph on all the tables solves the problem. the 2-3 shift is currently set to 69mph and 5500rpm. if it doesnt bang the limiter on the 2-3, I will increase it as needed so i can achieve a shift around 6000rpm

This:

Plus shifting higher during the 2 > 3 allows you to be at a higher speed and RPM for 3rd gear when it hits...which is probably going to be your last racing gear unless you're shooting for top speed and shift into 4th. Most street races I've been in are won or lost in 1:1.

I totally agree with you. I just need to fix the part where it bangs the limiter on the 2-3 shift. I made some changes today but it didnt help I'll post the file

And like I've said before, it's so weird. It'll only bang the limiter on the 2-3 shift if i go WOT from a slow roll or dig where it utilizes first gear. If Im rolling at 50mph and floor it, it drops down into 2nd gear, and itll upshift into 3rd at what I have it currently set to.

Could I possibly be missing something here?

a little update- my friend looked into the tune. he added some tq management and decreased shift pressure a lil. Also changed the shift points a lil. It seems to be shifting into 3rd @ wot now when I go from a 1st gear roll. Just needs some minor tweaking. I will end up going with a built trans because I dont like the feel of torque management and I'm hard on transmissions lol
