tspotter

it is your brake pad sensor. It is designed to inform you when the brake pads are getting very low on friction material and need replacing. It could also be a loose sensor wire if you know that the pads are good

Yeah, I did notice that the other day. Driving to the highway it was pretty bad but after a good highway run the problem seemed better.

The Lexus dealer want's $89 to test and see if the tranny has any stored codes. I think that unless he drives it with the scan tool attached during the occurrence he wont find anything.

pretty annoying.

I have a 95 ls400 w/ 85k. Whenever I take my foot abruptly off of the gas pedal while at any speed, the transmission jerks violently. It has been recently serviced (T-tech) but the problem did not go away.

The NHTSA shows a similar complaint on their website with no resolution and it refers to a problem with the ECU cutting out momentarily.

Help!

I use Jiffy Lube and they use a machine called a T-Tech for power flushing both the transmission and the coolant system. Works great and runs around $80 per system.
