Guys, wanted to throw a question out to anyone with a BL built trans or possibly any built trans.
I went to the track last week for the first time after installing my new BL trans and a 2800rpm stall. Made three passes and noticed that my car was shifting from first gear to second gear around 5600-5700 rpm... does this seem a little early for the first to second shift? It held every other gear just fine.

btw
94 tt, full bpu, pulled trac fuse, car ran 12.5 @114 on street tires.

Thanks for any feedback.

Any suggestions on what might be causing it to shift so early or what a fix might be?
more info about the car just incase
stock twins
Greddy front mount, downpipe, exhaust
vpc
avc-r (was running 1.21bar)
safc
New BL trans (less than 500 miles)
New 2800 stall
all new fluids
b&m trans cooler with a 7.5in pull fan behind it.

At the track I was stalling it up to about 2600 with the foot brake and then launching it.

Do I also need to remove the trac ecu (I already removed the trac fuse)

Thanks for any suggestions

I answered your question in the drag forum.

T6, you sure about those shift points? 7500 is awfully high with a high stall converter.

My Gforce shifted at the stock 6800 shift point.

Yeah, mine has always shifted at 7500 with the G-Force 8000 rev limit. Makes a huge difference in ET's, 6800 is way too low for APU.

What was your rev limit, 7500?

Nope, 8500rpms. I only used the higher rev limit so I could hold 3rd gear through the traps. My little 67mm quit making power at 6800rpms.
