Hi, Thanks for taking attention of my problem. I started noticing a problem last night after engaging into D gear. The main issue is that upon releasing the brakes after engaging, I find the car to not be moving much at all or even not move in some instance, and upon accelerating slightly, the rpm's increases for a bit before the car jerks forward greatly.

Some additional information;

• Problem seems to occur in this pattern - When I reversed, and engaged D after that i.E. When parking and adjusting.

• If I start my car the next day and go into P, there is no problem. • It occurred once when I was a traffic stop and moving off.

• One fault code but not sure if relevant - idle rpm's higher than expected

• Does not seem to have a transmission oil leak (according to a mechanic)

• Mechanic recommends taking the transmission apart and basically overhauling

• Mechanic suggests that replacing transmission oil will not help • Car has around 90,000 miles and is nine years old.

Do let me know what you guys think, as I got a feeling the mechanic is not diagnosing it right. Looking forward to responses!

If the transmission is slipping the oil will look dark and smell burnt, is this the case?

Hi. Thanks for replying.

Drained the transmission and found fluid to be brown and somewhat diluted. Mechanic said there were water in it and wanted me to overhaul the transmission.

Instead, changed the fluid and carried on driving - There were actually some improvements after which.

Today however, I took a look at my coolant reservoir and found it to be completely brownish, and it does smell like burnt oil. Shocked me because I thought I had just fixed it two weeks ago, when we found the coolant to be similarly brown. We suspected engine oil getting into the cooling system.

It got me wondering now, could it be that my transmission oil that's actually leaking and mixing with the cooling system?

Let me know what you think.
