I put my blazer in 4lo it hit rev limiter and never shifted. I looked at tranny data on my scanner it says 4lo signal disabled. I landed a 4lo input from obs harness to the ls pcm. Tune problem?

Not supposed to shift in 4-lo
That would defeat the whole purpose of a transmission. It will and can shift it's in the tune.Quote:

Tanz, sorry man, but there has never been and never will be a factory auto trans, 4lo equipped vehicle that doesn't shift thru all forward gears while in 4lo.
Sounds like a calibration issue to me as well.
Meh, wrong if I'm wrong. I will still sleep tonight.
Maybe i too had a bad ground from on the position switch.
Really? Please quit. You've obviously never used 4-lo, or at least payed any attention. I can barely hit 5mph in 4-lo and 1st, that would be preety useless.Quote:

People are allowed to be wrong around here once in a while, but you haven't earned the right to be a douche around here yet.Quote:
