hi...

Is there any special procedure for braking in a new transmission? I'm not refering to a rebuilt unit, but a brand new factory transmission from Mazda.

thanks!

 

Are we bragging about sourcing a "NEW" tranny or are you serious?.

Install the thing and drive it. When the cars were new people just drove them without worrying about how to break in the trans.

 

Tranny is a new one, never heard anything about it, but like all moving parts I would drive it smooth and not go racing the day you got it in or anything then drain it and go again.

Granted this is just MO, nothing to back it up, just what I would do or what I will do when I get my 6 speed/straight cuts in.

 

how much did you pay for your new OEM tranny?

 

I got it for 2200 + 109 shipping from Malloy Mazda. My old tranny had 173,000 miles on it and had never been rebuilt. There was a shop very close to my house (can walk to it) that was going to rebuild it for $1250 so I took it there. They tore it down and found the problem was some bearing that is near the pilot bearing, this bearing costs $700 from malloy and is inaddition to the regular rebuild. My reverse and 3rd gear were worn really bad. So total was going to be 2000 for rebuild or just buy a new one (BTW, mazda doesn't reman trannys, its kinda cool).

I realize I was losing alot of power from my tranny. With my new one shifting at 5000 RPM in first I can chirp the rear wheels, I never was able to do that before unless at a high RPM.

So I have a new engine, transmission, clutch and differential, shocks and all bushings in the last year.

 

oh, didn't know we were talkin about an auto... Hell I would have done the conversion for you for less than that

 

what are you talking about? where did I say auto? I have a 5 speed would never own any auto.

 

Why go drain the tranny after the first few drives? No one did that when the car was new either.

Install it, fill it, drive it.

 

Im really confused. Who said anyting about an auto conversion?

and turbo jeff...what about draining the tranny? I dont see any reference to that.

I was curious about the break in cause everyone breaks in an engine and in theory could be braking in the tranny too, I wasn't sure if its ok for me to go drag racing tomorrow (2 days after it was installed, lol)>

 

Turbojeff was referring to what jt-imports (Jason) said up above. I think ejmack1 thought you were talking about an auto because you mentioned shifting at 5000, thats all. Anyways, good luck with the new tranny, I need one too but I just plan on getting it rebuilt.

 

oh, shifting at 5K, I get it. I dont shift at 8000 every time, lol.

 

"With my new one shifting at 5000 RPM in first I can chirp the rear wheels, I never was able to do that before unless at a high RPM."

That made it look like an auto tranny owner

 

if it helps on my lunch break I shifted at 3000 rpm and chirped the rear wheels, lol.

 

I figured thats where he was getting the idea of it being an auto. You will have to forgive Eric, he is a little slow, HAHA, j/k buddy!!

 

What bearing is near the pilot bearing? I've only heard of the input shaft bearing going out.

I was saying IF IT WAS MY CAR, thats what I would do. Yeah there is nothing for a break in period, that I have ever heard.

NEW PARTS THAT MOVE;
Engine---Metal in the oil
Diff-------Metal in the oil
Tranny---I would assume metal in the oil.

Me personally I dont like metal floating around in my fluids and I understand its not suppose to be super clean, but I like as little or no junk in there as possible.

I change my tranny fluid every 2 months or less. No syncro problems or hard shifts (YET)....

 

In saying this, MAYBE this is why a lot of people have a LOT of tranny problems.....?

 

theres a little cage bearing between the input and mainshafts, but its $7 not $700.

 

Must be the cheap-*** Sears-brand winter P225s you've got on the car...

 

These are not Sears brand!! They pep boys Futuras!!!

actually they are crappy daytona tires.

 

What were some of the signs that your tranny was going out? Any particular sounds, etc...?

 

I agree with JT-imports..

If I had a new tranny, I would fill it, drive for couple of months and change the fluid again.. I've heard while back that some metal particle does float thru.. hence the little magnet on the drain plug..

 

The little magnet on the drain plug is why you don't need to change your tranny oil very often. I'm with Jeff. I would say every 20K miles is a good changing interval.

 

As usual turbojeff has the right answer.

 

So you just have a little drain plug with a magnet on your engine too and just change it every 20K too? Hummm not me.......................................

Im not making this an argument I just think its safer, whats wrong with being safe? im not saying to need to change as often all the time, but after just installing it I would be careful, nothing wrong with that..

Now if you want to change it every 20K after the first one then cool, depending on how you drive and what your fluids are this should be fine..
