hey guys I am in need of some assistance. ill start of by saying I did a ls swap in an obs rcsb z71. I took the easy route. carbed and had my 700r4 beefed up. I shortly realized how much I dislike carbs. so I purchased a stand alone harness from nelson performance and am going back to fuel injected. I figured mite as well run a electronic transmission.

so I picked up a used 4l60e. I plan on having a shop go over it. but what internals should I have upgraded to make it a reliable transmission behind a lq9 with intake headers and tune?

this does not have to be a full blown race tranny.
so far my list consists of. what else should I add in
sonnax smart shell
sonnax servo and od servos
aluminum accumulators

 

look into using the Sonnax Performance Pack.

 

Save the hassle and expense and go with the sonnax performance pack and vette servo.... new reverse input drum with wide band. i have the z pack in my 3-4 others prefer the bw hi energy, rest of my clutches are alto red eagle, i also went with newer rollerized internals with 5 pinion planetaries and a beast sunshell... Just my 2¢

 

thanks guys I will definitely be running the performance pack. the bw in the 3-4 clutches.

it seems from the research I have done the bw stays together better in the 3-4 then any other brand but for all the others it does not seem to matter

I have heard good/bad on the beast shell so if I can I am going to try out the smart shell

I try to start things out on a budget build but that snow ***** very quickly. lol

 

My budget build turned into something like $1600-1900 but i have a whole extra trans with nothing to build it for.... Lol

 

try living in Canada where we got hosed for everything price wise

would you guys suggest a hardened output being a 4x4 and running larger tires?

 

Yes..... Its a good idea as is a hardened input shaft... Havent personally broken one yet but theres a first for everything!!!

 

Thanks I know a couple guys around here that have snapped a couple but they seem more 2wd with big rims

Now here is my stupid question. The transmission I have is out of an 05. The computer I have tuned is a 411 set up for an 02. Is there any different in wiring internally or reasons those 2 would be incompatible?

 

No, they should be fine... The 4l60 didnt get the iss sensor until i want to say 07 or 08, iirc the wiring harness and solenoids are same up to 06-07 somewhere...

 

another random question trying to gather parts and part numbers. does anyone happen to know the part # for the bw 29 element sprags and the carbon wideband?
