Differential pin savers for A543?

[not2quick]

I'm finally getting my shadow's tranny fixed and replacing all my tranny seals. Do I need the diff pin savers for the A543? I know the turbo guys do it. How do you do it, and were do your get the pins?
Thanks,
Justin

all they are is a steel plate that you bolt in with 2 ring gear bolts. they really don't work. what is more solid is to weld the pin in.. however being able to service again is more difficult. I actually had to replace a customer's trans. I had installed case saver plates.... the idiot was beating the crap our of the car in reverse in a snow storm doing donuts... well I found one of the spider gears laying on top of the intake.

So it's not worth putting them in? I'm not abusive to my cars, but will be racing it everyonce in a while. It does hook pretty hard.

hard to say. I circle track raced the same 525 trans for 3 years with 350hp and never had a trans failure.

With a manual, you most likely won't need them. The main reason is gear oil. Problem with the autos is the differential sits in ATF, which is pretty thin stuff indeed! When one heats the hides with an open trans and the weight between the front tires isn't balanced, you'll get the dreaded one-legged burnout. This will spin the side gears super fast and gall the pin. ATF isn't a good lubricant for a high RPM/high load surfaces. The pin savers will not prevent the pin from galling, just keep it from flying out the diff and through the housing, sort of. Manuals has thicker gear oil, so the chances of galling are less. Everyone that I've heard of throwing a pin out the trans always had an auto.

that's not really true. these manual transmissions use ATF or engine oil depending on which one.

What kills the diff pin is massive wheel spin... which is easier in an automatic. here in WI when we get lots of snow, people with automatics will stand on the gas and with one wheel spinning the trans is shifting gears easily getting to 100+mph. with a manual, you don't normally get to high gear twisting 100mph with one wheel spinning and the other sitting still.

the difference or differential with one wheel spinning faster than the other is what makes the spider gears move. one wheel turning 100 and the other stopped creates a ton of load and heat on the pin and spiders. then suddently kablooeee
