Rebuilt my 4R!

[DEEZUZ]

Found a few flaws in the ATSG book and a few things they didnt detail too well. But was a decent read.

Did the triple disc and a transgo tugger kit.

How do you guys like the shifts?

I believe this is Tony Wildman Daily tune too

I think the only thing @Mark K will be mad at is we re used the Mechanical diode. The truck is a 2002, dont know why it had that but I wasnt going to do the update. Ill regret that later. We swung the parts by our buddy whose a trans builder and he didnt sweat the diode issue.

 

[DEEZUZ]

Also, can someone walk me through the steps that the trans is doing? 1-2-3-convert lock, then OD?

 

[DEEZUZ]

 

[dsberman94]

123 lock od is what mine does normal driving.

 

[Tiha]

Those shifts look a little lazy, what size did you drill too?

Did you do the convertor mods?

That shift sequence is correct. My TC lock up piles up on my 2-3rd shift. You have a much better split than I do.

Maybe the TW chip is affecting all of that. I have TW tunes and love them more than any other but I had him omit trans programming from my tunes.

 

[DEEZUZ]

Converter mods?

You mean pump?

 

[Tiha]

Which tugger kit did you use?

The HD had a convertor mod to swap from a pwm to solid on off. Pretty awesome, with the right convertor it feels like another gear.

There are pump mods separate from convertor mods.

I guess if you got the cheaper kit you didn't get the spacer plate that you drill holes in to control shift firmness either?

 

[DEEZUZ]

yes i got the plate. we drilled the minimum holes and i think it shifts too harsh,


my only real complaint is how short 1st gear is. im into 2nd gear halfway through a turn.

 

[dsberman94]

Looks like 2nd gear hits at 15? How fast are you going around corners? It sounds like a healthy shift, quick and firm. No sliding into the next gear.

 

[DEEZUZ]

Happens too quick no?

 

[dsberman94]

I don’t think so. I drove mine a bit this morning. You probably just notice it more now because of the firmer shift. It could be changed in the tuning if you really don’t like it.

Ok cool

 

[dsberman94]

I’ll get you a quick video of mine tomorrow when I bring it home from the in laws. To me it seems normal though.

Yes.

2nd gear lockup is where its at though! If you can tune it for that.

The last mechanical diode was built in the spring of 2001. That's several months before 2002 production started. When was your truck built? The month and year are on the data decal in the driver's door opening.

Maybe someone swapped the trans for a 2001 at some point.

We swung the parts by our buddy whose a trans builder and he didnt sweat the diode issue.

He is probably the only trans builder out there with that attitude. Or maybe he is expecting to get the work when it does fail. And it will.

Listen to that guy^^^^^^^^

Does his tag tell you anything?

And this is the diode right?

 

[Mark Kovalsky]

That tag does have the trans build date. But I don't know how to read it.

And that one way clutch looks like a sprag to me, not the mechanical diode.

 

[EPA]

Tag read BD-2D19
Buid date- year, month, day. 2002, may 19th
This is how i have known the tags to work, I could be wrong but so far it's been accurate.
The month is a,b,c,d ect... A being January.

Ok I'm just a little confused. That gear wih the diodes inside of it, I thought that's the dreaded mechanical diode?

Once it was installed it only turned one way.
