HI, im having some problems, hope that one of you guys can help me out a bit.

I have a 2004 6s, on a really hot day I cannot shift into reverse after starting the car. It takes me a few attempts the move the gear stick past the lock. I turn the enigine on and off and put my foot on and off the brake several times and it seems to work.

Most of the time the car is fine. Mornings it slips straight into gear.

I recently replaced the brake calipers but i dont see how this could be connected to the problem.

please guys any help would be great, i dont want to be stuck somewhere without any gears one day.

thanks.
