Well,same thing again,tranny has gone out.I know the 86 tranny is a piece of **** but jesus,I can not keep these things togethor.The gears in these babys are some weak mothers.Its always the same thing,take off--then bamn!noise out the ass,reverse locks up and first does the same thing--have to shift to second very quik just to get it to keep rolling.

Is there any thing to beef up these units--?any ideas on an upgrade for these years?

why not just put a T2 tranny in it and be done? It will bolt up, and with the money you have already spent you could have bought one already...

I didnt know a t2 would bolt right up.If so--hell its done.Can I get some confermation on this---and is there a cut off year that will match up

confirmation--sorry

It will fit, you will either need to install a T2 rear and driveshaft along with it, or have a custom driveshaft made.

Any year t2 drivetrain will bolt right in. You just need the corresponding series t2 crossmember and Y section for the tranny to bolt up.

Is your car heavily modded?



IMO, there is no need for a TII drivetrain unless the car is putting out 200+ hp. If you're going through three trannies in a year and half there's one of two things wrong. A) You're using trannies that aren't good to begin with or B) you need to work on your shifting strategies.



That said, I recommend finding a n/a tranny that is in good condition (read: low miles or quality rebuild). There are a number of people online selling them, through both retail fronts and when parting cars. I have driven a number of series 4's for extended periods and have yet to have a tranny fail completely on me. My current tranny has a worn out 1st gear synchro (no problem, just needs a double clutch move) and a previous one had a slightly worn third (again, just requires full engagement of the clutch and a well matched rpm on downshifting). The other two I've had extended experience (thousands of miles) were also both high mileage (100k-150k+) and gave me no troubles.



Also, run synthetic fluid in your tranny, especially if you're shifting hard often or not matching your rpms really well. I use Redline MT and strongly suggest it.



Good luck.

yeah something sounds amiss there.

Whether or not he is highly modified or not, the problem is the trannies are weak, He may be shifting wrong, he may have some issues buying odler transmissions, but the fact remains we all know the T2 tranny is more capable than the N/A trannies. Upgrading to the T2 tranny now will also facilitate the process for a T2 swap in the future, sine we are never happy with the power of our cars. I suggested the T2 upgrade to get him on the right track.

I would tend to agree, if your using junk yard/used transmissions

then you can expect them to blow up again.



why not get yours rebuilt and get a warranty with it?

Well,I know for A fact its not me.

I never had any problems with the tranny in my t2,

or any of my other cars ranging from a chevy s-10 with a 400 small block

to a 68 camaro with a 454 ---I miss the old days.

I do drive it hard---But I have never seen trannys come apart so bad in my life as i have seen with this car.It always starts off with a small vibration like the pilot bearing is going out.Then one day--bamn!rumble,rumble,rumble.she locks up in first,Locks up in reverse---I have to baby it to get it back from where ever I am at.The last time it dynoed in at 177 at the wheels--and after reading about the tranny,mazda was pushing there limits with this unit to begin with.Any upgrades would probably bring trouble to it. https://www.nopistons.com/forums/pub...1047683358.gif My father owns a couple of cottmans transmission shops in north carolina---and trust me when i go down there I see a ton of 5 speed n/a trannys out back completely fucked up.I just believe being so hard on it,and the added power is a disaster waiting to happen

You're a perfect candidate for a TII drivetrain since you are pushing the upper limits of the power the n/a tranny can hold.



I am opposed to the swap because 1) Added weight to the drivetrain 2) Nearly all racing classes require stock driveline 3) MOST failures (at least in road racing) come from bearing failure 4) a properly rebuilt tranny is better than stock (a good rebuilder modifies the tranny slightly) and 5) I am satisfied with my n/a power (that statement regarding a desire for more power angers me, but I'll leave it at that).



Good luck

"n/a for life, forever"

If your dad owns some trans shops and you know there is a problem then why do you keep driving the car?



Doesn't make sense to me.

i think u are havign **** for luck or mayeb u gotta do somethign about teh driving, or mayeb its somehting in your car that breaks them, u sure u dont have a turbo and u launch at 8500. most people i ride with are beign too DAMN HARD ON THEIR TRANNIES for no freakign reason, u can get aroudn just as fast but ne nicer to teh car.
