Hi, i from Ukraine and i need your help. a have Tahoe 95`

Please tell me where the automatic transmission speed sensor (Tahoe 95god.) - The situation is such that when switching from one to 2. also on 3. transfer of the motor much yelling, picking up speed, about 15-20s. and it seemed as if the transfer switch \ "Maybe emergency mode \", Oil on black and smells burnt (2 days ago bought 8 liters of new oil Dex 3 + oily filter replaced) The old oil was the same as it is now a new (, diagnosed in Automatic we can not do anywhere else no equipment to carry it out, help please tell me what could happen and where is the speed sensor (sin upon him) thanks in advance.

Sorry for my bad english if something is unclear ask again...

 

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.

 

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

 

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.

 

Try this web site. I know you are in the Ukrane, but perhaps it can help you identify it.
