Will a 6 pinion planet gear work in 4L65E

[joecar]

I'm wondering... you might be able to use the reluctor input drum/shaft if you use the stator support that goes with it... check with PATC if the ISS style stator support works in a non-ISS transmission... if it does, then you would be able use that input drum/shaft.

Ask them if both parts fit into a non-ISS 4L60E/4L65E.

Hi Joe,

I just got back from visiting SEMA and brought the parts back with me, everything is sorted after being looked over by your government people (they left a note in my cases to say they checked everything too - nice).

The 6 pinion gearset looks like a nice piece. The drum aasembly I got is the later one which is strengthened and the shaft hardened, the shaft is the later reluctor shaft. I think these parts are from the 4L70E, and although I dont have ISS on mine, the new stator support shaft sorts this. I also bought some other good parts to build the box.

I hope it all works, although the expert consensus is that I should've gone with a 4L80E for the 1/4 mile.

Cheers Gareth

Hi Gareth,

Hey cool... there's no feeling like having new parts in your possession...
the next best feeling is having your engine or transmission apart in pieces and looking over everything in detail...

Ok, so the new stator support allows the later/strengthen/4L70E input shaft to fit in the 4L6xE... I'm filing that for future use.


There's quite a few people running strengthen 4L60E's that are doing just fine... Sure, the 4L80E/4L85E is designed to be heavier duty, but it would still need to be strengthened... the 4L6xE is a simpler box compared to the 4L80E, and simplicity usually always wins.

I think that the closer spacing between 1st and 2nd will remove a lot of induced stress; and the 6 pinion carrier, besides being stronger, spreads the load more evenly.


Please post lots of pics of your parts when possible...

Cheers mate

Gareth,

Can you please do this for me when you can: count the teeth on the sun gear, ring gear, and one pinion.

Thanks, I appreciate it.

Ok I'll post up when I take some pics.

What I have been told is that although the parts will help the box to take extra torque/hp, (as the vendors advertise), it is how that torque/hp is applied that is the problem, and you can't get much worse than kicking it's ar** out of the hole on a 1/4 mile. (They say the parts I have got are supposed to take 600 ft lbs - but not how?)

Anyway, we'll build this and give it a shot and let you know what happens, but I have been told the T42 tune has to be absolutely spot on for it all to go together.

Also been told that whatever you do with a 4L65, the computer is the limitation and it would be a good idea to look at installing the sonnax vacuum kit to take it out of the equation (you have to fool it into thinking it is doing the job though).

gareth,

38,70,16.

Cool, thanks, those are important to know...

From those I calculate 1st gear at 2.8421...

I misplaced the tooth counts for the other gearset...

Do you also happen to know the teeth count for:
- OEM front/input gearset,
- OEM rear/reaction gearset,

Thanks I appreciate it.

[joecar]

Oh, I think I found them:

OEM front gearset tooth count:
sun = 34
ring = 70
planet = 18

OEM rear rgearset tooth count:
sun = 34
ring = 78
planet = 22

Oh, I think I found them:

OEM front gearset tooth count:
sun = 34
ring = 70
planet = 18

OEM rear rgearset tooth count:
sun = 34
ring = 78
planet = 22

Those are for 4L65E with 5 pinion gear?

It seems to me that those are for OEM 4-pinon and OEM 5-pinion gearsets.

Partial sanity check:
sun + 2*pinion = ring
34 + 2*18 = 70
34 + 2*22 = 78
