I FOUND AN HONEST CAR-REPAIR SHOP!
My mechanic told me I had to get a complete transmission flush for my Audi. $350.
I found Crompton's online, told them to do the job, and left my car for the afternoon.
In an hour they called and said they did not think it was needed.
When I told them my mechanic said the transmission oil was dirty, they said, "Let's check more deeply."
An hour later they called: they'd checked the oil in two different ways, did a drive-test, and said, "Nope. Your oil is fine."
But on the drive test, they noticed the transmission was slipping a bit, which tipped them off to check the oil level: it was DOWN two litres. Not good.
So they topped it up, probably saving me from a blown transmission in the next months, because no way I'd have known.
The kicker? the manager, Ben, didn't charge me a penny. Even when I insisted. "It's just a couple of litres of oil..." he said.
I've already sent my brother here. Really refreshing to find this place.
