Can anyone explain the differences between the kits they offer? I want to put one on my truck, but I don't know enough to know which one to buy.

This one is called a shift kit.
TFOD
Firmer Lockup-Reduces: OD Planet Failure-Soft Shifts-Drainback-Lockup Slip/Burn-Vent/Side Seal Leak.
Has resistor and High Temp rings for heavy duty use.
HD & Perf Truck Reduces no shift complaint.

This one is called a reprogramming kit.
TFOD-HD2
Automatic Shift; Street or Full-race;
Holds 1st, 2nd and 3rd to any rpm;
Backshifts to 3rd, 2nd and 1st at any rpm.
Competition combination. Has resistor.

How does it Hold 1st, 2nd and 3rd to any rpm? When does it shift? Which kit is better? In the real world how different would they drive?

Thanks
John

 

I was wondering this also a while back. I think you need the TFOD kit for daily driving and mild mods. The TFOD HD2 is for racing. I'd say go with just the TFOD, but I'm not certain.

 

I'm going with the race version... It will hold 1st, 2nd, and 3rd when you have the trans shifted into that gear is how I understand it, but IDK... Smart Guys, HELP US OUT!

 

the TFOD kit is just an improver kit for shift corection complants.
the THOD-HD is a HD - hot rod type kit and it is recomended to NOT install the option of holding gears in diesels as it also will allow manual down shifts at any speed!!!

If you do not install the option of holding gears is it any different than the other kit?

John

 

It might apply more pressure; thus, harder shifts between each gear. You might even have to manually shift between each gear with the race version. Some of them are like that, not sure if the HD2 is like that tho.

 

I ran the TFOD-Diesel kit for a long time, and I liked it pretty good. It definately helped my transmission hold the power. It would also hold any gear to any RPM if you put the gear selector in that gear, but they do that stock anyway i think. It would downgear to 2nd at any speed, you just had to be sure and not downgear to 2nd over 50mph. it did firm the shifts up. it upgeared a little early at light throttle, and also a little early at wide open, but you can always shift it when you want with the gear selector. Overall the kit is very well worth the money, and I would just go for the TFOD-DIESEL kit.

So Where Can You Get One Of These Tfod-diesel Kits ?

 

yes there ar severel more things diffrent. to list a few. a disc you install in the front servo to lock the apply pin to the body. a stiffer rear servo spring and spacer to eleminate the cushion.
a mod to the throttle valve. more line pressure ( diffrent spring ). diffrent hole sizes.

Yes the TFOD-diesel kit would be the one that you would want to get for yourself. It will bring your line pressures up to a variable 90-140psi (vs 50-90psi stock) and allow you to shift down at any speed. As stated shifting down from high speeds is NOT recommended. You will notice much firmer and positive shifts (especially while towing) and you can actually tune the shift points if you follow the directions when installing.

For those wondering where to get one; PM me and I'll get you set up.

 

I was talking to someone about a shift kit he had installed on on his chevy with the mighty 6.2. He said what he did not like was when he was driving in slippery conditions the 1-2 shift being more firm made the truck harder to control. Is this the norm or just the unmanageable power from the 6.2?

John

 

oh that's a good one... But seriously now, it would be related to the firmer shifts, the minimum line pressure with the shift kit is the same as the maximum line pressure on a stock tranny. We have an 82 Chev with a tweaked 6.2 and a Transgo shift kit. It's one of our mobile service trucks now, but when we lived in Florida it hauled our stock cars to the track every Saturday night and it always had some pretty good get up and go for a naturally aspirated IDI. It really isn't too bad to drive on slippery roads so long as you drive like there's an egg on your accelerator

Remember NOT to get the SK-TFOD-JR shift kit. It's gotta be the TFOD-Diesel. Just search ebay for TFOD. They have some just for the 47RH and not the 47RE, so make sure you're transmission is compatible with the kit you're getting. Second gen trannies are kinda mixed, so best bet would be to call up the dealer with your VIN and ask them which tranny you have. Or maybe someone here can decode your VIN for you.
