This vehicle has never stalled out, over heated or not started. Major recent repairs. Whirring sound under the hood. Blows out cold air. Starts perfectly. However has no acceleration. But when ac is on it accelerates and shifts just fine

It sounds like the TIPM is going out. Lets do a CAN scan to see what codes are stored, please go over this video to show you how.

Here is the TIPM location, it is easy to replace because it self learns. Please go over this guide and get back to us. Check out the images (below).
