Sure... I'm not at all saying he shouldn't make the drive. I just know how much more fun my car was with the 3.29s and I'd have had a real hard time behaving for 50 miles :p

thanks for the offer but thats a bit of a drive. i'd love to get hp tuner but cant justify 300-400 dollars right now... wonder if i can find someone local that needs lt1 tuning and i'd swap with them lol.

regarding the gear swap how many rpm did that raise your at say 60-70 mph?

3.29's are definitely more fun than stock, I catch myself hitting the loud pedal just for effect!

ordered my transmission, did go with the 3.29 as well. still need to work out the tune part of it, but if all else fails i'll just have tep tune it.
also got a transmission cooler, i went with a bigger one so i can cut the radiator out of the loop. i'm sure its full of crap from failing transmission.

Awesome, you won't be disappointed. I fell in love with my car all over again with the TEP tranny and 3.29s.

Also FWIW if you didn't bypass the radiator you'd have to flush that crap out anyway or TEP's warranty is void.

Flush your radiator transmission cooler with a product called "Kooler Kleen".

http://www.lubegard.com/~/C-184/Dr.+Tranny+Kooler+Kleen

This way you can run both the factory cooler inline with your aftermarket unit, thus allowing the fluid to be brought up to temperature much more effectively. Your shift pressures are also affected by the fluid temperature thru the TCM.

Has anyone here bypassed the factory cooler?

Anyway if your still worried about contaminants install one of these between your new cooler and the transmission....

http://magnefinefilters.com/Magnefin...lter-R012M.htm

I have had very good experiences with re-using factory coolers when properly flushed and installing the magnafine filters inline after the tranny cooler. Ford actually will not warranty a reman tranny if you do not have one of these intstalled.....

i'd assume someone else has bypassed it, when i asked about a transmission cooler dave gave me a few options and bypassing was one of them.

i might change my mind depending on how nasty my current fluid is.

I have mine bypassed. I'm using a 20k btu cooler, temps are about 25-35 (164-177 cruising) degrees lower than stock on average. Before the cooler, 194-205 cruising.

i think i'll end up having dave tune it. that way there wont be any finger pointing if something goes wrong.

i just stopped driving it, it was getting bad and i figure i'm saving myself a tow bill, plus the thought of it breaking down with 2 kids in the car.
dave said the transmission would be about 3 weeks, so i got another week and a half... probably start pulling it apart next weekend.

With the engine supported with this you can drop the entire engine/transmission cradle and you will have all the room in the world to drop the transmission from underneath.

If you have dropped any FWD transmissions in the past, you will have no problem dropping this one, its very similar to other GM FWD cars, as well as the Ford Taurus layouts.

The most aggravating part is the transmission dipstick, you need to do your best to prevent damage and bending, the bolt is a feeler process.....you know how that goes.

If you get stuck, just reply here or PM me I can help....
transmission should be here today, so i'm gathering the things i need. i'll just do the 4x4 post, what do you end up hooking to the motor? i was thinking about getting a ratchet strap and chain to hold it...

transmission never showed up, but did work on getting the old one out.

got the front wheels and cv pulled out. i had to cut the bolt off both tie rods, they both got to where they were almost off and then froze up, i probably should of cleaned the threads before i started unbolting them. of course the 1st side took me a couple hours had to figure out what i was needing to remove and what i didnt need too... 2nd side took 15 minutes lol.
every where i was reading was saying leave the a arm on and just undo the ball joint at the end to separate it... i found it easier to just take un bolt the arm fro the engine cradle.
so far the only issues besides the tie rods is getting to one of the transmission cooler line. the vertical one is in a place its not easy to get a wrench on strait.
i've got it pretty much to the point i'm ready to unbolt the transmission. going to wait till my new one shows up so the engine isnt dangling all week on my home made support fixture.

almost got it back together. man i would love to have a conversation with gm on why they thought it was a good idea to have 4 transmission bolts going from the transmission to the block... then throw one in the back going from the block to the transmission. i think i spent half a day trying to figure out why i couldnt get it apart... and finally wedge my arm in their enough to feel a bolt... then had to put 3 foot of extensions together so i could get it from the passenger wheel well.

that and the whole inch in space between the transmission and the frame... doesnt give you much room to pull it back to clear the flywheel.
if you dont have the engine and transmission perftectly level its not coming out.

got it back together and running... what a nightmare, a ground broken on the engine side and i spent a day trying to figure out why i couldnt get it started.

anyway the car shifts great now, better than it has ever before. i still need an alignment and a minor leak on the cooler line.

anyone know what type/size of fitting the cooler line is going into the transmission? i hate to by a whole new line just to cut it up so i can use it with my transmission cooler.

pretty much anwsering my own question but figured i'd post in case anyone cared...

The fitting and the lines are two different parts... the line just has a flare end on it that goes into the fitting and is held in by a clip. the fitting has an o-ring in it that can fall apart when you are removing the line... dealer has the fitting for 13 bucks so its not to bad.
