I have an unopened can of Trans Tune I bought about 2-3 years ago. Does it go bad if it’s sealed sitting in the garage? It has been in the garage in the hot summer and cold winter on a shelf.

Hi Dan. Your can of Trans Tune is just like new. Trans Tune will last many decades if the seal is unopened. Even so, Trans Tune works best when opened and added to fluid. Don’t forget to use it!
