No, actually when I am slowing to a stop the car is in neutral while braking, the whole dad chewing on me about not holding the clutch in any longer than necessary thing.
Grinding noise going from neutral to 5th

Ok, I know it can be hard to teach an old dog new tricks, but perhaps some revmatching and downshifting is in order?
With todays EFI systems, downshifting while coming to a stop saves more fuel than having the car in neutral with the engine idling. The caveat is that downshifting, while taking some strain and wear off of your brakes, adds a bit more wear to the shifter and clutch. But with proper revmatching, the transmission wear is reduced greatly.
LOL. My grandfather told me the same things as your Dad when I was learning to drive. (yes)
Sounds like your Dad had a few bad experiences with transmissions. I know my grandpa did. Once Grandpa drove his fairly new Rambler back to the dealer in the only gear it would drive in, REVERSE, across town. Mom said they got a lot of stares sitting at the traffic lights. (eek2)

My dad didn't go that far, but got close. He drove my 85 Mustang GT home for 3 miles through 4 traffic lights using only 5th gear, thank god that 5 litre had great torque!!
A lot of reading!
How does the tranny shift if you use it according to our banter?
If it shifts fine, there's nothing to fix.
FWIW... I occasionally get a bit of a synchro mismatch when I try to accelerate quickly and shift from 1st to 2nd. I'm not sure if it's tied to a certain RPM range and the FBW throttle response or not. But that is my suspicion. I seem to have an RPM blip around 4K RPM.

It does fine if I do the rev match, but I am having a friend who is a mechanic flush the trans to make sure I didn't leave any fun little metal bits floating around in the fluid (eek2) I do appreciate the input
Doesn't the Mazda3 have a 6-speed manual transmission? As long as you are replacing the transmission, might as well see if you can get that installed (and if so, how much $$$).
A good start. I think you'll be OK after that. I don't think this tranny was designed for quick shifting anyhow. Your friend will be able to give you the truth. (direct)

Here's my 2 pence: Both my Ford T-Bird SC & my CRX were MT. Both of them had synchro probs after I took ownership of them. What I used to do was rev high when starting from lights, etc, then skip gears. My most usual skip was 4th, but I've skipped from 2nd to 5th, or 1st to 4th, you name it. In only a few thousand miles, I was having major shift probs on both cars. I was even getting locked out of gear sometimes. I am not sure what tranny is in the 90 T-Bird, but being RWD it was either from a 'Stang or truck, so it wasn't a sissy.
So, when I decided I wanted to go MT this time, for longevity (think about all the 300,000 mile cars you have seen - how many were AT?) I knew I needed to change my habits. I now always go in order, except for the downshift when coming to a stop. Hopefully, I am not doing anything wrong anymore & can keep this car for a loooooong time without any tranny worries.
As an aside, the days of coasting are long gone, opus. Power steering is standard, so the engine needs to engaged all the time, 'cuz if it cuts own when coasting, you are SOL on the steering dept. Sure, you are most likely strong enuf to power it, but what happens when the engine stalls, you don't realize it, you're going 65 into a corner & suddenly you have to apply more muscle to make the turn - A. you understeer right off the road or B. you quicky overcorrect & oversteer into a spin & end up off the road. Either way, its not pretty at that speed & the TN troopers would not be happy when called to clean up the mess.
Whatever you decide tho, good luck to ya.

I've heard about this ground wire process before, but have never seen pics of the process. If you happened to either take pics, or could produce a pic guide I would be more than willing to try. Thanks !!
The thread got me into reading 'Auto Mechanics Fundamentals' (M.Stockel)..
A really old book.
Some comments it has about shifting:
=====
"When shifting the transmission, it is wise to hesitate in the neutral range for a brief moment. The synchromesh unit depends upon a limited amount of friction to synchronize the speeds. By hesitating a moment and then shoving the stick smoothly into the desired gear, the synchromesh unit will have time to function.
So called "speed-shifting" is very injurious to the synchromesh gears. and for that matter, the entire drive train. Speed shifting maybe justified when a vehicle is entered in competition. At any other time, it is considered the mark of a poor driving".
========
So I think the original poster was right in that by pushing on the clutch - and give it sometime (for the cluster gears to spin slowly) - one can shift gently into any gear without any grinding. i.e. no need for rev matching. This is true if the car or transmission is new.
But because it is already a habit, one never know how often 'speed shifting' have occured in the past.. and hence damaging the syncrhronizer.
