Hi guys
​​ i am new here

I hope you can help me

my car chevy tahoe 1995 2door 4WD

i swap the engine to Lq4 6.0 2006

tire size 305/70/16
I added Truecall cooler 40.000

the problem with transmission
3 times I changed the transmission over the course of three years
All of them I bought from Junkyard

last gear 2004 4l60e 5 pinion 4WD
Now work only 1
so I am thinking of buying a building kit that will be useful for my cars in the desert and daily use

Please help, thank you

 

Stop getting the transmissions from the junkyard, unless you are going to rebuild them.

5-pinion planetaries are NOT as good as 4-pinion, it is a subject that has been discussed many times on here.

Read some of the stickied threads at the top of the page; after you have read through a few of them, start asking questions.

 

Well, its not that 5 pinion is not as good as 4. Its just useless in 99% builds. It is the aftermarket cheap 5 pinions is garbage. The OEM one is good. Just useless.

For a mater of fact, @Kfxguy did destroyed few 4 pinions in the past and switched to OEM 5 pinions

 

I'm not sure of your question but hope this helps.

Whatever It Takes Transmission Parts will have a kit to meet your needs. You can order from their web site or find a store near you and purchase your parts locally. Locally is cheaper most of the time.

 

The OEM/ Stock/ GM/ Hydra-Matic/ ACDelco (whatever you want to call them) 5-Pinion Planets are inferior to the 4-Pinion Planets...
End of Story!

 

I keep reading guys saying this same thing. My experience has been exactly the opposite, honestly. I have been out of the 60 game for some time now, and pretty much all I build is diesel stuff anymore, but I've certainly put in my time with the 60's. I, personally, found the OE 5 pinion carriers to be stronger where they spline onto the low roller inner race; right down at the base where it transitions from the spline lugs into the actual carrier. The 4 pinion carriers are undercut right there, with the bottom of the lugs having been machined away, while the 5 pinion carriers have the lugs running all the way down. I have seen several performance builds across my bench over the years with the 4 pinion carrier broken right down at the base of that transition. I have not seen the same with the 5 pinions. Again, just my experiences...

I'm not trying to start a war or anything, and I know this is hashed to death all too often. I'm just curious where you're seeing the rear planets fail...both 4 and 5 pinion.

 

Dynamic396, did you get my reply to you earlier today about if the problem you were seeing was rear planets only, or front planets too?
