I just got a '01 F150 V6. How much control over the T/C lockup can I get with a chip? I hate the unlock when you let off the gas and every little bump in the road the T/C will unlock. Can a chip solve my problems?
The trans works pretty good otherwise.

Depending on what chip I am useing in my diesel, the converter will not unlock till I tap the brakes or I get down to about 35 mph.
To me this works like it should.

Thanks

 

Hi Scar,

What you'll want to consider is that the lockup characteristics are of necessity going to be much different for a 4.2 V-6 F-150 as compared to a Powerstroke diesel, those 2 engine's respective power curves & characteristics are pretty much diametrically opposed.

The 4.2 V-6 has a particular characteristic of being especially weak below 2500 rpm, while the diesel has a *tremendous* amount of torque everywhere, and it's peak is at a way-low 1800 rpm. This alone makes all the difference in the world in what those characteristics really need to be.

The Superchip is going to improve this, and make the vehicle much more enjoyable to drive. The Superchip for the 4.2 V-6 is rated at a maximum potential gain of 25 hp & 31 lbs./ft. of torque in that engine. It will also clean up the shift characteristics of that automatic transmission quite a bit, removing the various delays, retards & transitional deficits that make it a bit of a slug to drive.

I would suggest giving us a call and let us go over this with you in detail, so you'll have a good feel for what to expect & what is done, etc. Our contact info is just below.

 

Thanks Mike.

I am quite aware of the difference in power between the PSD and the V6. The V6 has plenty of power and torque for what I bought it for. It's this converter unlock on coast that I really don't like and was hopeing a chip would address.

I know that Ford does this to improve mpg but it sure is hard on brakes. It drives me nuts to have to ride the brakes all the time.

 

Just do what I do in my V8, shift it down into 2nd gear on a hill. Its not much work and you won't have to use your breaks as much. Also take off the overdrive if your going too fast for 2nd that keeps it in 3rd.

As far as the transmission being "smart" enough to sense your going downhill and downshift automatically. Well then you get into really expensive transmissions like the Alisons. There computer will sense your going downhill and automatically downshift.

If this isn't what your looking for in an answer then I don't know what your talking about.

 

It has nothing to do with the trans being smart and downshifting. All I'm talking about is the torque converter unlocking when coasting.

I'm not talking about stopping without the brakes. Comming down a slight hill you should not have to drag your brakes to maintain your same speed.

 

Nope sorry, don't have an answer for you there. I don't know much at all about how the computer tells the torque converter to do stuff. But if you unlocked the torque converter so your could "coast", woulnd't that like putting it in neutral? Then your truck would go even faster down a slight hill requiring you to use more brakes. The only thing that would slow you down other than your brakes is your engin through your transmission, meaning you have to go to a lower gear.

Help me out Mike if I am still missing something???

 

This is an excellent example of some things just not translating via the written word. That just doesn't work well in these situations, which is why we suggest using a phone to discuss details, always.

The only way an automatic is not going to accelerate going downhill is either via application of brakes or via compression braking, either from a downshift or unlocking of the torque converter. Defeating the unlocking of the torque converter under deceleration is not a smart thing to do in general, especially if the vehicle is ever going to be driven in inclement weather. Automatics already have far too little compression braking thanks to the combination of mechanical configuration, low-compresion engines, etc.

The bottom line is, we'll do just about anything within reason if it's requested in a custom program, though we'll always make our suggestions on whether what the customer wants to do should be done, the pros & cons, etc., and then it's up to the customer to decide, we're here to please!
