Hi,
I have a 99 RX300, i just had my transmission fixed. The car just stop working - and i have realized that these transmission problems are common in RX300s. But the real problem now is that right after i picked it up from the shop, the check engine lights came on, also the trac off lights come on after few miles - since it was saturday the aamco shop where i had my transmission fixed was closed and i was travelling. when i took it to the aamco shop near my house they said it was some oxygen sensor code. I never had the check engine lights come on at all before. My question is how could fixing the transmission lead to check engine lights on?
I tried to reset it by unplugging the battery, but after i plugged it back in, the lights came on after few miles.
Please help me with whatever you can!!!
