99 OB downshifting
Posted 13 July 2003 - 10:39 AM
After listening to a buddy brag about Subarus I finally decided to take the plunge and bought a 99 OB w/50,000 mi. I have several Subaru related questions but I'll only ask 2 of them now. 1. I read on another subaru board (can't remember which one) that the 99 OB came out with something designed to downshift on hills but, since it does it so abruptly (and inappropriately) the company decided to offer a less agressive version and the dealer would install it free...the dealer I took mine to said they had never heard of this problem or any free replacement. can anyone shed some light on this? 2. Is it normal for the engine to knock at startup and for about the first minute or two of driving (after warmup)? Thank you for your help and this board!

I too have a 99 outback with this problem, and I've chosen to ignore it since I generally drive around in 3rd anyway. The hassle of dealing with the subaru dealership isn't worth getting it fixed.
Does anyone have the number of the TSB?

If you care to find out more, I think there are some saved topics in the archives. That or I could post the "Shop Talk" bulletin pertaining to it.

In 1997, Subaru engines (1.8, 2.2 and 2.5) are more fuel efficient, more powerful and have a flatter more usable torque curve than their predecessors. To achieve these seemingly opposite objectives, it was necessary to bring many improvements and modifications to the Subaru engine line up. Following are some of those improvements:
1. Mechanical valve lash adjuster (reduces friction)
2. Light weight pistons (reduces inertia)
3. Short skirt, Molybdenum coated pistons (reduces friction)
4. Increased compression ratio (improved power output)
5. Improved cylinder head design (improves cooling)
6. Inertia resonance induction system (improves breathing)
The only drawback to these enhancements may be some engine noise after a cold start-up. This noise is a consequence of the engine improvements and is not a precursor to future engine problems.
If a customer complains of cold engine knock, please reassure him/her that no permanent engine damage will occur. If the noise persists and is still clearly audible when the engine is warm, please consult your DASM.
Please do not hesitate to contact your DASM if you should have any questions or comments.

Tell me that can't damage the car.... It was redlined and would not shift out of third until I came to a stop and went through all the gears while stopped.
I just try to be careful in situations where I know it may act up.
