Which shift kit/valve body to buy???

[USMCmarauder]

I am putting my 100 shot of NOS in this week and think a valve body might be in order to save my tranny. Any suggestions. Through my tune, Lidio firmed up the shifts, but I'm looking for a little more. Thanks

If I read Zack's reply correctly, he's telling you to "do the J-Mod", and I agree totally.

The J-Mod was developed by Jerry Wroblewski, one of the original designers of the AODE/4R70W, and no one knows more about this transmission than he does. The J-Mod costs practically nothing, yet is far superior to any of the commercially available shift kits.

Didn't Jerry chime in this morning? Maybe you can PM him for more info.

I must be missing something. I don't see J-Mod in the link.

The J-mod will firm up your shifts for next to free. It's well documented.

IIUC, Art Carr has a 'kit' including the right size bit and everything.

If you're not scared of working on your own tranny, the Level II kit with J-Mod, clutches, stubshaft, clip, and tailshaft lube circuit is only like 500 bucks.

So you'd recommend the J-Mod for a 2004 MM tranny?

He will custom make a valvebody for you to whatever power level/shift aggressiveness you want. You can then swap out your stocker for it.

Too expensive for what you get!!!

I obviously would recommend the J-mod (do you know I hate that phrase). What I really need to do is make an update to the article for Marauder specific vehicles. Some of the things I recommended when I wrote that, I was able to get into production at Ford.

What needs to happen is this; we need someone with a stock Marauder trans, a hoist, and few days to try some different things. I'm sure Dennis would offer his shop.....any volunteers?

Hey Jerry, remember how much fun we had rebuliding those Ttransmissions in your garage that day?

You might like to know I no longer have a problem with other people's trans parts inside of mine!!

I believe Glenn is interested in a tranny upgrade. His is still stock and it has a Trilogy s/c on it. I would volunteer but I already have a LenTech.

Jerry,
Volunteer number one! I have all the necessary equipment at my disposal to do this and document it (Including before and after high-speed data-logging). I also have 3 cars with 4R70W trannys to work with (I.E. I wouldn't be put out having one down). If you'd like to discuss it, PM me your phone number and we'll see if it is mutually feasible. I live in the Tampa Bay region of Florida.

Thanks,

J

Lonnie at Blue Oval Chips makes J-Modded valve body's for only $200 bucks if you're afraid to work on your own. I'm not sure if he went up in price though. I got my J-Mod for my '95 a long time ago, and it was well worth it.

Now I'm confused. (Not at all unusual!) I just had the full Level II trans kit from Dennis installed. Tailshaft lube circuit? I thought that was an extra mod that I missed, and should have had done at the same time.

I still have to get the braided line and fittings installed though to get the tailshaft lube mod going though, correct?

Thanks much,

Norm

Norm, I dunno. I ordered my Levell II, discussed it with DR and when I got there a built tranny was waiting and we traded cores. Call DR for details. I think you gotta weld the bung on the tailshaft or swap tailshfts to get the lube mod. It may have been extra, I don't remember. I had a lot of work done all at once!

Not to be to dumb, but what exactly is a J-Mod?

Since this was named after you and we all consider you to be the final authority on our transmissions I am
sure we would defer to your wishes, tell us what you prefer.
