Harsh shifting ive had same problem since day one. i have an 08 touring model(turbo) that only has 8k miles on it. its a year old and garage kept. when pulling out of garage to drive it is 2 blks to main street. when accelerating onto that street and shifting from first to second there is often a very violent slam forward. it only happens cold, no more than once. i have been hesitant about taking to a dealer in spite of my warranty because it doesnt set a check engine light and it is intermittiant and as a tech myself fear hearing the words no problem found. has anyone else seen or heard of this, any help is appreciated

losing bost (turbo boost)?????? have turbo here?????????

get the car serviced, you can not fix turbo problems, some are very complex.
gee 21 years old and just 1200 miles per year
just 3 miles per day used, only to church under full turbo boost
LOL (grin) sorry !

that turbo part is called a waste gate, and opens only as max boost is reached, so the engine does not explode. (5psi? = par)
that is what it does and can stick , jam and leak and for sure
full of carbon, driving just 3 miles per day. and nasty job to clean all that out.
so get (er) done, find a shop and tell them your turbo is acting up $$$$$$$$$$

Engine is missfiring, bad spark plug or ignition coil
let me know how you get on

here is some info. I hope it helps.

This is a code relative to shift solenoid malfunctions in your computer. This is a known problem on your model and Toyota released an updated PCM to correct the problem.
While you can replace the PCM yourself if you are out of warranty, your dealer will need to code your VIN to it in order to get rid of the check engine light.
The warranty coverage is 8 years or 80,000 miles from new.

The details of the bulletin are below:

TSB UPDATE NOTICE:The information contained in this TSB supercedes TSB No. TC014-06.

Powertrain Control Module/PCM) to reduce the possibility of this condition occurring

I think you need the dealer to look at this.

YOU HAVE A AIR LEAK IN THE TURBO SYSTEM CK HOSE'S MY 2006 3500 SPLIT THE HOSE HIGH WHISTLING SOUND. LOW POWER / AND LIMP MODES TOO. ORDER THIS AND BINGO IF FIX IT . YES THE OLD TURBO RESONATOR HAD SPLIT TOO. I did not use the o-ring from the old part I found one 1 side down that fit tight around the new part. A loose o-ring is going to weak air too. Got mine on ebay.

Hi,
The 1st>>2nd shift on the Subaru 4EAT automatic transmission can be more abrupt, but 3500 is too high.
Is there any delay when shifting from Park to Drive?
Does the Power light flash on startup? If it does, you can pull the codes by following these instructions.

This trans has 'bands' that can be adjusted. I'm not 100% sure they affect the 1st>2nd gear shift, but maybe they need adjusted.

Take a look @ ultimatesubaru.org/forum and http://bbs.legacycentral.org. 2 sites dedicated to Subarus.

Good luck,
Td

There is a Bulletin on this concern, and it is a warrantable condition for 8 years or 80,000 miles so you are still covered by the factory warranty.
The problem is a logic issue in the PCM. The correction is a new PCM with updated software.

yes I do believe you can easily get 200k out of her. I have seen a few volvo's with over 250k on them. As long as maintenance is kept up, she'll keep purring

The code 45 in a later model is for the AWD control module causing harsh shifts. On a 2000 model the warranty per recall is 8 years and 100,000 miles. For your model you can try calling a dealer about recalls.

I have a 99 olds intrigue 3.8l Autozone computer states poor electrical connection or short circuit, or failed vehicle spped sensor or drive gear mechanical fault. speedometer works sometimes and drives great next time it raises rpm and speedometer does not work. Where is the speed sensor or where is the elctrical circuit I can check to see if connections are good.
