Just left the tune shop lowered my shift speeds by 17% and lowered my shift points and still bangs the limiter. maybe i need to contact frost.

Are you leaving it in drive or over drive ? Mine won't shift by it self any other way.

[sloroller]

I'm leaving it in overdrive

[bills98ta]

They need to lower the mph and rpm shift points for each gear. Take it back and try again... What are they tuning with ? HP Tuners ?

[bills98ta]

My 1 - 2 shift is set at 29 mph and 6200 rpm to achieve a 7000 rpm shift. My limiter is at 7400...

[sloroller]

my begining shift was at 6000 and shift at 6800 limiter set at 7000 now he bumped it back at i think5600 with a shift point of 6300

Set at 5600 with a shift poing of 6300. This is just me but it sounds like the tranny is starting to go. I would double check with Frost. When your shift points were set higher I would not have said that. I would have backed down or gone back to stock shift points to see.

Are you on stock Rod Bolts?

Are you on stock Rod Bolts?

H-Beam Rods / ARP's and lunati +12cc dome pistons / 5.3 heads done up yielding 14:1 CR. 4600 stall / 4.10 gears. 150 shot too / ect.. .The tuner might want to do some comparison's on other transmission tunes to tweak it in...

I ran my stock bottom end with the same set up, until it pulled a rod bolt.

He has to lower the mph shift points too. They can be zeroed but I didn't.

Any ideas about breaking the tens on motor with my set up na motor?

[bills98ta]

I had my stock bottom motor hitting 10.8's with a 150 dry shot. Walbro 255 fuel pump & 30lb injectors at the time. And a little more tuning ! LOL

[sloroller]

Went back to my tuner and dialed it in a little and fixed it, went to the the track and had no problems. thanks for the input

Not bad at all !!! 4000 stall, I'm guessing a 1.4X - 60' ???
