GMC SKI

hey guys

Just wondering if anyone is using the bigstuff3 to run the spark and fuel and allowing the Stock ECU to run the transmission.
I'm having issues with the tranny not shifting stuck in 3rd
Need to know what perimiters the stock trans needs to shift
My speedo works and my tach is working
Currently sharing the TPS and Crank sensors
Any Ideas ? trans is a 4l80e
I did get some shift solenoid DTC also p1810 and p1860

Where are all the BS3 Guru's ??

Hairball

You could upgrade your BS3 system to include trans control. There are other postings of people using the BS3 system with 4L80E transmissions.

I'd call Kurt @ W2W, he's a guru for BS3, and if you buy it from him, he will give you excellent tech support.

I run a BS3 but am shifting my RMVB T400.
