Tranny advice

[micus]

Hey all, looking to beef up the tranny with a billet triple disk unit (probably from ari) and a transgo shift kit, I believe its called the tugger kit. It's in an early 99 PSD with the 4r100. I was Hoping these upgrades would be sufficient for an edge tuner or perhaps a custom 6 position chip. Also I'm going to add an aftermarket trans cooler. Any thoughts or suggestions?

I like my tugger Kit, but a bts or john woods valve body is a better deal imo. Those are also cheapest if you pay to have the tugger installed. The shop did mine twice as it didn't shift like I wanted, so they ended redrilling the plate, there's also an anti drann back piece that goes somewheres that comes in the kit

Shifts like a mild hot rod now.

I have been told that the shift kit may not always be the best because if the sleeves inside the valve body are worn that your still operating with a unit that is not performing like it needs to however if you buy a john woods valve body he checks and replaces those parts if need be.

And a 6 position chip can be tuned to adjust your shift firmness as well. However if the valve body is already warn it will not do much because it cannot handle the extra pressure and just bypass the extra fluid.

If it was me (and i am in the same boat as you at the moment) buy a valve body.
Then you can chose a 6 position chip from a reputable company they can tune it to your valve body as well.

a good TC and good VB (recommend the BTS.. but a tugger2 is also a great piece) will be GREAT and hold tons of power.

Although, I would never suggest an edge. Custom chips are the way to go with the 7.3

To make the stock tranny last as long as possible, I'd look into a tc, vb and bigger trans cooler.
TC: precision industries stallion is the best out there by far.
VB: JW, BTS, or sonnax are the ones I would use.
Cooler: Either a 6.0 or a tru cool 40k.
