Garage Door Opener Upgrade

[KenNTennessee]

My 2012 GMC Sierra SLT has the factory garage door opener, which is the Lear product caller learcar2u. I have been using it ever since I purchased the truck new in 2012 and it worked fine with my 2003 Craftsman opener. However the circuit board went bad in the opener and parts are no longer available, so yesterday I had to replace the opener. When I could not get the truck programmed after about 9 unsuccessful attempts I called the help number in my owners manual, got a recording that the help line had been discontinued and to use the web site. So I went to the web site where they asked for the model number of the remote that I was trying to program and returned a response that it was incompatible and could not be programmed.  So out of curiosity I tried several other manufacturer's garage door opener model numbers and discovered that the learcar2u transmitter can not be programmed for any of the new openers currently available on the market.
A little further research I found that GM only used the Lear product through the 2013 model year and in 2014 switched to Homelink. Homelink is compatible and I had no problem programming my other car which deos have homelink.
So I'm wondering if I can just purchase the transmitter for a 2014 GMC Sierra and replace only the transmitter in my truck.  It's in the overhead console and appears to be similar in design.  Does anyone kow if it will fit?  I hate to spend the $100 for a part only to find out it won't work.  Thanks.

Call the opener manufacturer and ask them. Should be a fix. I've had them send me necessary parts free of charge when when security has changed
