    transmission question

    not sure this is the place to post this thread...

    My syncros have gone out for 2nd gear completly and i have asked BMW of Fairfax how much it all is in parts at there cost without the Bcca membership (that i still havent gotten yet cuz of the lack of $$$ on my part) and it looks to be not too bad of price. well here is the big question at hand, do i spend the money to get the parts to just turn around and go to some other place to have them installed since BMW of Fairfax wont touch it because they dont do that kind of work or do i just look into a tranny replacement instead? and if i go that route what kind of costs am i looking at??

    one reason i am in my own mind leaning tword replaceing the entire tranny with either a used or new one is also because the car has over 200K of milage and i have no real way of knowing if the tranny was ever replaced in the past as well.

    so any input or advice would be a huge help on this subject.

    thanks in advance
    Eddie R.

    At that mileage, the best idea would be to get a nice lower mileage trans from a part car. If you keep your eyes peeled, you can find sub 100k trans for $800 or less.

    You might want to try an transmission fluid change. This might silence the synchros. Use Redline RTMTL or RLD4ATF depending what the sticker on your transmission states. Some manual transmission M3s (my '95 included) call for automatic transmission fluid. Redline fluids are $9.95 per quart (the job takes 1.3 quarts). I have been able to purchase these fluids at Advance Auto Parts, as well as online from www.bavauto.com.

    car-part.com. I just recently picked up a 100k mile ZF trans for $200. From the LKQ in Frederick. This one came from an E46 328, so it probably wasn't abused too badly, either.

    **** no, don't use Redline. Redline has enhanced and/or caused synchro issues in every single car I've used it in.

    Use Royal Purple if you have to try something aftermarket, otherwise use BMW MTF-LT2. It's a kick ass fluid (unlike the previous OEM ones).

    Nick325xiT,

    I don't claim to be an expert, but please explain how many and what kind of BMWs you had these synchro issues in? I don't doubt your claim, nor am I here to defend the honor of a company I don't have a stake in. What I do know, is that I have driven the 5 BMWs currently in my driveway hundreds of thousands of miles with Redline in the transmisions and the differentials. Absolutely none of them have had a problem. If I am endangering my vehicles, I would really like to know how. Again, this is just my personal experience with the product.

    In my experience, the ZF 5 and the Getrag 6 are awful with Redline. It's either caused or worsened 2nd gear grinding/crunching issues in these transmissions for me. Generally, Redline fluids feel great for a period of 1-4 weeks and then go to shit.

    Additionally, Redline fluids are TERRIBLE in the cold. I've used MTL, MT-90, and D4-ATF and they all exhibit the same characteristics.

    It is not exactly tropical here in Southern Maryland either, but I've had none of the problems you describe in any of my cars. I do take it easy on the transmissions in the winter while they are warming up. I consider that standard procedure. I guess it is like everything else: "Results may vary."

    The math for me is very simple. With Redline, 2nd is likely to grind when cold. With LT2, the only time that's ever happened is when the car was parked outside in Connecticutt (interestingly, Michigan wasn't cold enough on the same trip) in January. I'll forgive double clutching into 2nd when it's chilled to zero. Redline does the same thing cooled to 50.
