4R70W Fluid and Filter Change...how hard??

How hard would it be to change the transmission fluid (incluidng the torque converter) and filter with the 4R70W transmission?

Haha...yeah. I saw that after I posted.

What Mercon V oil do I need to buy? Is there a specific brand, or is it just any ATF that says it's at or above "Mercon V" specs?? I saw RedLine Oil on Summit Racing (seemed like that was all they carried that was labeled "Mercon V", but it's like $9 a quart no matter if you buy it by the quart or gallon!! If I need 13 quarts (planning on installing an aux cooler, might as well)...geez!!

I've noticed a couple of brands at auto parts stores for ~$3.50-4.00 per quart. Some posters here have posted they've used AAMCO fluid. I'd suspect the Valvoline Mercon V fluid is ok. I even know of one who's using Amsoil ATF. I'm not certain if Motorcraft Mercon V is available at retail stores, though. Motorcraft's website may help answer that question.

All-in-all, a leading name-brand should be ok to use, especially if it meets or exceeds the specs.

Hmm..I'll have to call the dealer and see how much the Motocraft Mercon V is. If it's too expensive...I may take my chances with a cheaper name-brand oil.

As for an auxiliary cooler...would I bypass the radiator, or would I hook it up in series with the radiator? I figured in series...the coolant could run through the radiator and normalize with the engine coolant temp, then run through the aux cooler to cool down a bit more and then back to the tranny. ORRR...would it benefit my engine to bypass so the tranny isn't heating the engine coolant??

Is this the filter I want? (PN# FRM-FT1167): http://store.summitracing.com/partde...5&autoview=sku


What are the opinions on Valvoline's Mercon V (PN# VV360)? It's the only oil I can find locally (besides Motocraft which is expensive) that specifically says "Mercon V". Everything else just seems to say plain "Mercon" equivalency. http://www.partsamerica.com/ProductD...rtnumber=VV360


(I like the "Shudder Protection" label on the bottle. )

Also, what are the opinions on this cooler kit? (PN# BMM-70264): http://store.summitracing.com/partde...0&autoview=sku

B&M makes good cooler kits, I have one myself.

I have never used this one myself, but looks promising.

Haha, that's a little steep for me. I'm trying to limit myself to $50 for the kit, hopefully less than $60 for fluid, and $20 or less for the filter. The fluid I mentioned above is around $3.75 a quart, or so. I priced it out and it'll be about $57 for 14 quarts after tax.

I like to buy from Autozone myself...like 14 bux for a filter and I buy the Coastal Mercon V cases, I think it's like 35 bux for a case and works well for me.

Kind of a side note. How often do you guys change your tranny fluid. I looked in my hanes manula and it recommends every 6000 miles. If that is the case then that could get real expensive real quick. Any help is greatly appreciated.

Pretty sure for your AOD at the least it is 15k miles, I go 20 to 30k with my 4R70Ws, the AOD in the 89, hmm, I do it everytime something goes wrong, like the rubber cooler lines burst or someone that drives my car hits the pan on a small import.

Expensive is 14 qts of Mercon V!

30,000 = 40,000 miles

I've heard a good rule of thumb is 30,000 miles. Since I'm lazy and don't want to deal with draining the TC, I figure I'll fluid and filter change every 15,000 (about once a year for me, pretty much). I just changed the fluid, and without draining the TC I got 6 quarts out of it. If it holds about 13 quarts alltogether (I did install a tranny cooler), then that's about half the fluid. Should be alright. :-D

I too am looking into doing a fluid change. My car has only 67000 miles on it. The fluid looks new but it shifts hard into 2nd gear and slugish into overdrive. Or should I do the Jerry mod at the same time. I have read alot of the tech articles but I am confused some.

I just did this last weekend. I used the Advance Auto store brand oil @ 2.98qt. I got the 24,000lb B&M cooler kit for $50. Don't skip draining the converter;it's easy and gets out as much oil as dropping the pan. I flushed it out following the tech article and I'm sure there couldn't have been more than a half quart left in it out of the full capacity. So far, it seems to have gotten rid of the intermittant shudder it had before.

Do the J-MOD and change out the accumulators to the new style and check the springs. Drain the pan and the torque converter. I put all the springs back in, but I will probably remove the 2-3 one and maybe one of the 1-2 springs also, we'll see what it is like after I get a tune.

It is all there, I wanted to understand what each change I did was going to do, and it is all in the writeup. I changed some of the sizes from just doing the mild/300 hp settings for things like quicker reverse engagment and first gear, but other than that, I stuck with what was recommended.

I added a cooler at the same time as well.
