firming up 1-2 shift without j mod

I rode in a local guys bird a while back that really shifted hard on the 1-2 shift
it would chirp the tires every time.
He worked for ford and he said the trans tech there just cut a spring .
Any idea on what spring he was refering to?
I would like to try this on my tranny.

Just remove the lower 1-2 accumulator spring and it will do this.

All he did was remove the lower 1-2 spring i bet. That's part of the j-mod... you're much better just doing the whole thing, it's actually better for your transmission.

You just remove the whole spring?
Do you have to drop the valve body to do this?
Are there any special tools involved?
Any pics or other instructions will be helpful.
thanks

Here's a link to a site a friend of mine put up about doing the J-mod: http://www.cardomain.com/memberpage/496399

Look on the second page for details on removing the spring. Also, you do not have to remove the valve body for this, just drop the pan, if this is all you're doing. You'll need a big set of heavy-duty snap-ring pliers to remove the snap-ring - small ones will just break the tips.

to remove the 1-2 bottom spring you dont have to drop the valve body. all you have to do is drain the fluid drop the pan and the 1-2 accumulator bore is visible. you need an in/lb tourqe wrench to re-install the pan and a pair of snap ring plier's to romve the snap ring on the accumulator bore. while your there you should just do the whole mod since you will be 1/2 way done. if not though at least drain the converter too and replace all the fluid with mercon v and install the udated 1-2 accumulaotr and the updated top spring.

Ok thanks alot.
So all I do is remove the pan,filter?
and i should see the 1-2 accumulator.
I just remove the bottom spring?
will the accumulator be loose without the spring?
or will it go back togather smooth?
I always ran Lucas semi synthetic racing fluid in my tranny and it stays clean
and shifts ok.
Thanks for all the info

Sorry for the thread bump, but is removing the spring bad for your tranny in any way? It's something I'll probably check out if not.

Nope. You'll probably need to change the spring anyway. The 94s had a problem with broken springs.

You should read the 30 pages so you understand how the tranmission works. Plus reading that article will answer most of your questions. We don't recommend reading that article just so that we don't have to answer 101 questions, there is a reason to read the article.

Nidex, removing the spring will not damage your transmission as Rodeo Joe stated.

OK if you dont want to answer 101 questions why post and tell me that?

OK Now I took the spring out tonight and it was a snap.
I would say it was easier than changing the oil.
The shifts are alot snapier no more pause between 1-2.
I also installed the updated piston.
1 more question (I dont think I hit 101 yet) Is there suposed to be more than 1 spring there? The reason I ask is everyone calls it the lower spring but I only had 1 spring. So why not just call it THE spring
I still dont chirp the tires on the 1-2 but that quit when I installed my converter.

THANKS FOR ALL YOUR ANSWERS GUYS

That's the way Ford built them. They only put one spring in there in the 94s, on the bottom. When putting it back together, the blue spring goes on top of the new piston.

OK thanks Mr. Joe
So the Blue spring is that the spring I took off the bottom or is it an
updated part?
Also when I install the new spring will it shift different? Harder softer?
thanks for being patient with me.

The blue spring is the updated part. You already have it back together don't you?

its gonna take more then just the spring to get some chirps. You should drill out the seperator plate. The chip will give you a nasty bark when combined with the Jmod.

The chip increases the line pressure which decreases the shift lag, because the fluid fills up faster, Then when you drill the seperator plate it increases fluid volume. Thats why they both work well toghther

Hey guys i got a question, i went and took my tranny pan off to start the first part of the j mod. When i went to take the snap ring off i pushed the bottom case up a little and the whole thing got stuck. It took me about an hr to get it out. I had to unscew a small bolt up higher and basically try to wedge it down. Anyone have that problem with the 94's. The bottom spring when i took it out was broken so that was the cause, but i'm just seeing if anyone had the same type of prob?

Broken springs are common, but usually its not hard to get the cover off... maybe part of the broken spring wedged it in somehow?

Hey guys i just finished with my jmod, but i kind of have a problem with the new tranny cooler line. I'm running through the radiator and then through the new cooler but the fitting that i used on the radiator so i could hook a line on keeps leaking so i just put the old setup without the extra cooler. Is there a better fitting that is one piece instead of a compressed fitting, because its leaking right and that point. By the way i love the way it shifts a ton better

Is it a B&M cooler? The reason why I'm asking is, a few people up this way installed B&M coolers last summer and had the same problem. Go to AutoZone or Home Depot and get another fitting. Something with those that came with the cooler didn't seal right.

MY B&M kit came with fittings that didn't work. I just went to local store and came up with a few that worked. I cut my tranny line down below the engine to tap in easier as well. But if you don't want to do that, just get some new fittings.

I cut the stupid ford fitting off the top line, installed a normal fitting on the end and reflared it... then put on the ones that came with my 24k B&M cooler and all was fine in the land of Oz.
