2005 chevy blazer won't shift into first

Asked by May 10, 2014 at 10:06 PM about the 2005 Chevrolet Blazer LS 2-Door 4WD

Question type: Maintenance & Repair

Today I change the tranny fluid in a friends '05 blazer. On the back of the transmission (transmission mount end) there are two electrical connectors. Underneath them is a hair thing wire wrapped around what I assume to be a coil. I noticed as I was putting the pan back on that one of the wires was broken (the one on the left if your laying underneath it with your legs sticking out of the driver side).

The trans now won't shift to 1st in Drive or if manually shifted to 1st, it only takes off in second. I assume that the problem is that wire I broke. What is that part called? Also, is that the problem or is there another reason why the trans is in limp mode?
Thanks for any help.

Disconnect the battery and fix that wire.. its wires for the shift solenoids

what you saw is a shift solenoid. Loosing one you will loose 1st and 4th gear. I have a feeling that's what happened.

Thanks for the reply's, after doing a whack load of searching, it looks like it was the 1-2 solenoid. Thanks again for the help.


I would change all the shift solenoids personally
