I am very pleased with the overall purchasing experience with 1A Auto. My payment was processed immediately and accurately, and I received the part 7 days after I ordered it, which is really commendable because it had to be shipped to Canada and cross the border. I received the part, and installation was pretty easy. The only snag I ran into was that the 2 terminal connector had the wrong terminal and would not fit into my factory wiring harness. All it took though, was to take my old harness and wire it to the new shift actuator. Even with that snag, I would still rate it overall as excellent. The part is fully operational and my 4x4 is back in perfect working order. Thanks 1A Auto

The instructional video made repairing my 4x4 a snap. The part was an exact fit and now all four wheels can get me out of trouble (sometimes all four get me in trouble).
Fast delivery, Perfect fit and connection.

I ordered this part and had it 2 days later. It was a perfect fit. It was very easy to install using the online video. It took about ten minutes to remove the old one and install the new one. Fired up the truck and it engaged the 4 wheel drive instantly. Problem solved. 1A Auto is the best. I get all my parts from them!!!

You said it would fit my 96 Tahoe but the plug on the wire did not match up. I cut the old plug off and wired it to the new unit and made it work.

After watching the video, I immediately ordered the part, and the r n r was as easy as watching the vid. Had I known this last winter, I'd have fixed it then. My driveway sucks in snow, so 4wd is imperative. It was almost impossible, even wit a run at it, which was also difficult due to traffic

If you're a thermal actuator kind of guy good product. I had to change mine every year regardless of how much wear-and-tear I go through or how much usage, but spending a few hundred dollars on a new four-wheel-drive system with a pull-locker circuit was a better way to go for my truck. Instead of waiting for the thermal actuator to work pull in second n go
Perfect

My 95 Silverado has a floor shifter for the 4x4 could this still be an issue or are the 4x4 actuator's only needed for the truck with a push button shifter?

The actuator is wired by the way of the floor shifter. I want to recommend the ALL ELECTRIC actuator (comes as a kit with instructions) it is an upgrade from the gas type. I had 2 of the gas type go out before I upgraded mine to the all electric actuator. A little extra work to install the extra wire but well worth the effort. I bought mine from 1A Auto and never a problem sense. My truck is a 93 Silverado 4x4,

I have a 1995 GMC with the 4 wheel drive on the floor. This actuator is needed for the 4 wheel drive to work. It is down on the front axle on the passenger side. Check to see if you have voltage down at the connector before buying this part. If no voltage then the switch up on the transfer case is bad.
