iam getting ready to get my 2001 dak V6 3.9 / 42 trans w/ O.E.M. cooler. with stock engine and exhaust. i know who will rebuild it. but i think i might want an over size oil pan. aluminium, steel? but not to tall, with a real drain plug. i looked on the internet and just got confused. ideas?

Mr.4spd

12 years for the oem setup sounds reasonable. That's what...150K miles? I'd save my money and go stock again.

moe7404

well no only 120,000 miles. BUT i am MUCH harder on trucks than any one. i am just glad i do have the money to do it. and think a better oil pan is what i need. but it might take a few weeks.

If it is still available ? The Mopar performance 727 deep pan is a good buy !!!! or the one for the 904 I have the 904 version on my 32RH trans
adds an extra 2 qts of fluid

moe7404

yep a deep pan is something ill look at. all so a temp gauge. elec or manual? and of course ATF +4 fluid ONLY. i have experimented with rear end grease in a 727 with good out come. but not now days. the dak has an O.E.M. trans oil cooler.

moe7404

well i checked with mt trans shop. he answered my Qs to my liking. and the price will be $1,900. since i have known this guys since the late 60s i know ill be happy. so as soon as the gov sends me my tax refund ill be doing well.

3.9 needs another 50 hp !!!!

RacerHog

I with you Lynn.... Maybe even a Magnum....

moe7404

but for low speeds my 4.1 gear does just fine. i drive only in town 30 MPH to 50 MPH. most of my cruse speed is 35-40. when i changed from a 3.55 to a 4.1 my MPG went from 8-9 to 11-12. cause the O.D. comes in at 35 MPH with lite throttle. and holds 1300 RPM at 30 MPH lite throttle.

RacerHog

From all my teachings and sources..... The best fuel mileage is obtained at 60 to 65 MPH With all the manufactures as designed. Period!
For what it's worth...
Not saying you didn't get it...... Just saying..

Ok..... How About a Turbo... Boost it Babe !!!!!!!

moe7404

i didnt say i was getting the best MPG my TWK can get. its just that 99.999% of my driving is 30-50 MPH. today i found out that the IRS posted my refund to my checking acc. so it might get fixed next week. my trans guy didnt think an aluminum pan is needed. cause i have an O.E.M. cooler.

RacerHog

OK..Dont yell at me.... I'm Slow....
The dam Wind blows faster than you drive....Ok, I get it !!!!
Hope you get it fixed.
I'm just fun'in with you, I hope you know?

moe7404

iam not about to yell. i really like my friends here. but after driving since 1965 i still dont know why i cant get as good as MPG as others. i must have a heavy foot.

RacerHog

Ok... I got the fix !!!!!!!!!! I figured it out.... You got better gas mileage before 1965... Rite.... So after that you started getting worse mileage..... I got it.....
You started driving with both feet on both pedals at the same time... You are a 2 footed driver !!!!!!

moe7404

my o my racer you make me reread what i post. the thing is i never checked my MPG till i got my 2001 dak. not that even care now. i check it in case something is not right. i do drive funny car style. but i dont drag the brakes.

RacerHog

Just keeping you sharp old friend....

TVLynn

My driver Ed teacher gave me h3ll for that. 67 Impala 283 PG hit passing gear on the freeway on ramp

TVLynn

Lots of rebuild videos on YouTube if you want to try it yourself. You do need access to a press for the Overdrive unit. 42 is the light duty A500 ? NOT a difficult project

moe7404

just picked up the new trany. the main shift points are the same. and i think the new torque converter slips less. so it might get better MPG. now i need two new tires and front end alinement. then i want a coolant filter,

moe7404

update it wont shift down to 1 st gear even at 12 MPH. i think ill take it back. it might be the control cable going to the TV. i know where the holder of the cable is. but i dont know how to unclip the cable. i hope my trans guy can show me. iam sure ill want to adjust it some more.

RacerHog

Could be a hung up governor.....

moe7404

man o man i hope not. i was reading some pics and text.. i might be making it harder than it is. i might try to do it my self. years ago i modded the linkage on a 65 300 L. i changed the lever ratio to move the linkage less than stock. it turned out very good.
