I take it, it is shifting hard? There is a modulator valve (vacuum controlled) I believe on that model, not totally sure since I think you refering to transfer, I assume transfer case. My 96 lumina has a vacumm controlled modulator valve for shifting the transmission. I'd suggest replace it.

Thank you, I will take note of.

If someone else has more suggestions, or who is faced with this, help please.

It may or may not have a modulator valve, I am not totally sure. I'd think if you sensor was an issue you have a check engine light. Anyway look for this it will be installed on the transmission, also note the O ring, so unless you are fast you will need to drain the transmission again.

Problems with the gear shift. switches from 1-2 4200-4700 rpm, to 2-3 3000-3500 rpm, Motor strongly shouts...

Look for a vacuum hose to a device on the transmission, again, I am not totally sure of your model, however if it has a modulator valve, replace it first.

Vanek

Tell me what name\model valve is needed, And where to find his.

kevinkpk

I don't know if it has one, Look underneath the transmission, see if there is a vacuum hose going to it anywhere, then follow it to the valve.
