shifting too early?

[j221282]

noticed that when the car is cold it shifts fine, but once it starts to get some heat she starts shifting early, :mad2: it starts doing 45mph at 1000 rpms , anybody experience this ?

one to two shifts are fine, it almost skips 3rd and goes straight into o/d, its annoying

[Mr. Man]

Could be related to the fluid being more viscous when cold. Does your car have a tune? If not get one it will make the car a whole different animal.
Mo's or Alternative Automotive sell the best tunes for the Marauder. They will be located in the vendor section.

[Marauderjack]

Surely you meant more viscous when cold Mr. Man!!:confused:

[RubberCtyRauder]

The factory trans tune opts for economy, thus getting into OD as soon as it can. Do what Mr Man said and get a sct tune from one of our vendors Mo's or Alternative auto . They can sell you the tune and sct and ups it to you. Or can just sell a tune and email it if you hAve an unmarried sct

[Mr. Man]

Surely you meant more viscous when cold Mr. Man!!:confused:
Well I thought I meant less viscous as I assumed perhaps wrongly that the very cold weather would thicken the trans fluid more than what might be usual.
You are intimating that the trans fluid thickens when it heats up. If that's the case I was unawhere that is what happens as whenever I check the fluid when the car is warm the fluid always seem pretty thin and flowable.


Going to check the offical defination of viscous now :)

Edit:

Seems you were correct in correcting me. I was using viscous as a substitute word for flowablity not stickyness. So in the cold a sticky fluid would become more sticky and heat may in some cases make it less sticky.

Learned something new today, Thank you for pointing out my mistake. :beer:

Viscous means sticky, gluey and syrupy. So if something is viscous, you usually don't want to stick your fingers in it — that goes for boogers and maple syrup alike.

Not quite a solid and not quite a liquid, scientists like to say that viscous things don't flow very easily. They glop and slug around slowly, sticking to whatever they come in contact with. Think of making a batch of Rice Krispie treats: One minute the marshmallows are solid little rounds; the next minute they're melted into a web of sticky white goo that's somehow attached itself to the Rice Krispies, the spoon, the countertops, your nose, the front door, and the dog.

When it comes to oils, marauderjack is a force to be reckoned with. I only beat him once, back in '78.

[j221282]

No it doesn't have a tune yet , but I've driven other marauders "stock" and they don't have this problem , thanks anyways guys I'll try out the sct tune here soon

[whitey]

Give some more info, such as mileage, any mods, ever change tranny fluid, address, age, social security number, etc.

You changed it yesterday......cold is more viscous and hot is less viscous.....correct now!!:beer:

Perhaps when the fluid thins out it flows more freely thus activating the solenoids quicker??

Regardless I would try a tune and see if he's just dealing with FORD's funky (wonky...new word;)) shifting!!

Was it always doing this or is it a new problem?

Was it always doing this or is it a new problem?And this. ^

When was the last ATF change?

[RF Overlord]

Another possibility: there is a thermistor (temperature-sensitive resistor) in the transmission pan which tells the PCM the fluid temperature so the PCM can decide whether to use the cold start shift strategy. The cold shift schedule also delays torque-converter clutch lockup until the transmission fluid has warmed.

My ScanGauge will read transmission fluid temp...not sure if regular scan tools or code readers will do this as well, but it might be worth having it checked.

It's always been doing this, i just got the car with 94k now has 107k no tunes that I know of , I wish I was more savy with these types of things, I will be doing trans oil change tomorrow

[RubberCtyRauder]

Make sure you use a MERCON V trans fluid..not a 'all around trans flulid"

[RF Overlord]

I agree with RCR again...Mercon V only.

FYI, beware of Valvoline's offering...it is NOT licensed by Ford. Motorcraft, Castrol, and even SuperTech (Wally World's house brand) are licensed and easy to find. I've used all three with good success.

Of course, AMSOIL and Mobil 1 are good as well if you want to go that route.

Thanks sir I'll make sure

[cunaginc]

When I got my marauder there was an sct tuner under the seat but other then plug it in, I have no idea at all how to operate it, where to have a tune put on it, or anything. Any suggestions.

[RubberCtyRauder]

The sct plugs into the OBDII port under the dash sort ofnear center console. does it have the cord? You can plug it in and it will tell you if it is married or unmarried..marreid means it is locked to that particular car presently (not necessarily yours) as for tunes, I would recommend sending a pm to martyo here inthe forums..He has MO's speed shop, a vendor inthe vendor section here and can easily send you a tune designed for the Maraduer. You can also UPS him the sct unit and they can tell you what is on it (not specifics as in who might have tuned it) and can load their tune on it with options for gas grade, gear ratio etc.

I see this is your first post and you are in Lousiville? There is a maraduer member meet in Lousiville in a like 1 month..you should go. there is info on this site under the events sections.

[j221282]

I got the trans fluid changed along with the filter and gasket, but didn't notice any difference, no check engine light is on, 2003 300a with 108k recently did a tune up, but still shifts early into overdrive, anybody has any other suggestions ? I went to a transmission shop and the guy said its a engine problems , shifts one to two are fine, it skips third and goes straight into o/d, engine just loads up , I don't think 45 mph at 1000 rpms is normal

[whitey]

What speed does it shift into o/d at under light acceleration? Stock shift schedule will shift into o/d at 36mph. At 40mph, while in o/d , rpm should be around 1300 rpm.
