i didnt seriously look at chryslers because if the transmission failures. MY GF loves the 300c.

im good. the dreaded water in the oil pan dealer trick. no thanks.

[assasinator]

this is long but typical... there is no dipstick.....sorry if its too long. ive read review after review on the forums and consumer report about this transmission. my GF would OWN one of these if it wasnt for the tranny being so bad.

they change to something else i will relook at the 300C.


Here is most of the service TSB but the images will not copy over. Remember the chart has been posted here somewhere just need to look for it.

FLUID AND FILTER
DESCRIPTION
The oil level control is located on the electrohydraulic
unit (4) and consists of the float (5) which is integrated
into the electrohydraulic unit. The float is positioned to
plug the opening (6) between the oil gallery (2) and
gearset chamber (1) so that the rotating gearsets do
not splash about in oil as the oil level rises. The oil
level control reduces power loss and prevents oil from
being thrown out of the transmission housing at high
oil temperatures.
OPERATION
With low oil levels, the lubricating oil which flows constantly
out of the gearset, flows back to oil gallery (2)
though the opening (6). If the oil level rises, the oil
presses the float (5) against the housing opening (6).
The float (5) therefore separates the oil gallery (2)
from the gearset chamber (1). The lubricating oil which
continues to flow out of the gearsets is thrown against
the housing wall, incorporated by the rotating parts
and flows back into the oil gallery (2) through the
upper opening (arrow).

DIAGNOSIS AND TESTING
EFFECTS OF INCORRECT FLUID LEVEL
A low fluid level allows the pump to take in air along with the fluid. Air in the fluid will cause fluid pressures to be
low and develop slower than normal. If the transmission is overfilled, the gears churn the fluid into foam. This aerates
the fluid and causing the same conditions occurring with a low level. In either case, air bubbles cause fluid
overheating, oxidation, and varnish buildup which interferes with valve and clutch operation. Foaming also causes
fluid expansion which can result in fluid overflow from the transmission vent or fill tube. Fluid overflow can easily be
mistaken for a leak if inspection is not careful.
CAUSES OF BURNT FLUID
Burnt, discolored fluid is a result of overheating which has three primary causes.
1. Internal clutch slippage, usually caused by low line pressure, inadequate clutch apply pressure, or clutch seal
failure.
2. A result of restricted fluid flow through the main and/or auxiliary cooler. This condition is usually the result of
a faulty or improperly installed drainback valve, a damaged oil cooler, or severe restrictions in the coolers and
lines caused by debris or kinked lines.
3. Heavy duty operation with a vehicle not properly equipped for this type of operation. Trailer towing or similar
high load operation will overheat the transmission fluid if the vehicle is improperly equipped. Such vehicles should
have an auxiliary transmission fluid cooler, a heavy duty cooling system, and the engine/axle ratio combination
needed to handle heavy loads.
FLUID CONTAMINATION
Transmission fluid contamination is generally a result of:
• adding incorrect fluid
• failure to clean dipstick and fill tube when checking level
• engine coolant entering the fluid
• internal failure that generates debris
• overheat that generates sludge (fluid breakdown)
• failure to replace contaminated converter after repair

$44,680.

I mean, that's a nice car and would seem to perform well......but really?

[Sawyer]

I'd rather get an SS with 6K in mods...

[Entaille]

I think the old one was priced out of the competition. with the refinements in suspension, the power increase (and if the 8 speed tranny was offered), I think it's priced appropriately.

[a_Username]

Wow... TC on made a .6 difference in the 1/4 for them! BTW, a GT500 with the Electronic Package and SVT Performance Package goes for ~$55K. That's the difference between a non Nav, loaded Camaro and this particular SRT-8! I believe Dodge did a good job at pricing this between the SS and GT500!

[RAYSRT8]

I plan on having mine on the dyno after break in is over... From what I have felt it's under rated at 470HP... It is definitely faster than my Camaro was stock so I can't wait to see what it will do on the dyno.

I think a few owners have been in the 450-460whp range so its save to say its cranking out close to 500hp and tons of torque. I cant wait to see what happens when the put their new 8 speed behind it.

[newmoon]

Seems like the dynos for these cars are all over the place, i've seen a few videos of 420 rwhp and then a few as mentioned above at 450 rwhp, either way they are underated and nasty.

[HEMI DAVE]

I am gonna get mine on the dyno after I break it in......its def got some balls.

[assasinator]

dynos ive seen are more around 404-415rwhp. its not underrated any at all.

Remeber, when comparing SAE certified engine dyno numbers to billy bob' sgarage dyno there isn't a straight comparison. SAE is certified HP under test conditions in lab and are accurate. Once you get into rear wheel dynos, there are too many variables to make an accurate comparison. Saying and engine is over or under-rated based on RW dyno is silly. The SAE numbers are as accurate as they get.

+100

Not to mention, underrating was a thing back in the 60s and 70s when car companies really had to worry about insurance companies, safety lobbies, and getting their cars to qualify for factory stock racing with less than actual numbers... none of these things really apply today and SAE certified is about as accurate as you can get.

Besides Dodge would have everything to loose by underrating their engine when compared to some very tough competition IMHO

this is truth.
