Hi there,
Several days ago I noticed that my transmission started shifting hard, so I added a quart of transmission fluid and it fixed it for about a day. Next day on the way from work it started shifting hard again. So, I added another quart of fluid. In the morning I checked under the car and only saw a couple of drops. So, I drove to work and it was shifting fine. Later in the evening after running some errands the problem returned. So, it looks like the fluid leaks when the car is being driven. I also noticed that when the problem occurs the color of transmission fluid is almost beige - not a lot of pink or rose in it.
The car has 250K miles on it but I haven't done any transmission maintenance on it for about 150K miles. I was thinking "well, the fluid is pink, so must be OK." To my defense I did perform good engine maintenance
Can hard shifting be caused by trans fluid or filter not being changed for a long time? Last week I had to replace my leaking heater hoses, so maybe now something is leaking in transmission system. Given all that, what steps would you recommend to troubleshoot and fix this?
Thanks!
