Transgo reprogramming kit for the 350C....

[Freddie's Buick]

This is the Transgo reprogramming kit for the THM-350C.

This kit requires some drilling but it is ultimatly very easy to install.
The most difficult decision is the choice for the PR valve; street or competition.

I am not too knowledegable about racing so what can I expect from this kit if I choose competition via the PR valve?

Also I don't understand what they mean by full command, backshift to 2nd or 1st or holding on to 1st or 2nd at any rpm?

This is an automatic so does this mean control by throttle?

How firm do you need it to shift? The competition PR spring raises the line press. to give you more holding for the clutches & a firmer shift.
Full command, some trans. even with the shifter in 1st after a certain rpm it will shift to second, some won't allow a downshift until slowed enough. This kit will allow you to select any gear at any speed but it still retains the automatic function.

Hope I splained that right.

Not sure... I can only shift reverse, drive and low. Let me see....... what do they mean by 1st, does this mean drive? And does 2nd mean low? (The 350 only has reverse, drive and low).

Or do they mean the shifts in drive, @15 mph-1st shift, @30 mph-2nd, @55 mph-3rd. (Again, I can't shift with the shifter... it's automatic in drive).

I don't really want it to bang into the shifts in drive, so I think I would prefer a smooth shift...
