ECM, Where is this located Options

[trdproven]

I'm thinking I am having a bad ECM, car is having problems shifting. Plus I smell something burning in my car at times. Wondering if I can find out where the ECM is, I can test and swap with a good unit. If anyone is parting their car and will sell an ECM to me, I will keep that in mind to buy. Can anyone confirm a 3sfe ECM is the same as a 5sfe ECM? Thanks!

I've read online that a flush is not good for your car. Some state, make sure you have enough money for another trans if you're going to do a flush. Is that a myth?

There's nothing wrong with a flush if you have a properly maintained transmission, we do them all the time at work. Now from personal experience, if you haven't at least changed the fluid every 30k then you're almost better leaving it alone. I've had a couple cars come thru with about 70-80k (both were Fords tho) on them that wanted a tranny service, I drained the fluid and pulled the pans and there was a lot of fine metal shards and dust in the fluid. Both of them after the service had to be towed out to a transmission shop for a rebuild.
