I'm in the process of rebuilding a 2002 4l60e and and going through final check of clutch pack clearances . I've gotten all set to approximately .040 in except for the low reverse pack and it measures .065. I'm not finding alot on the setup of the min and max tolerances for the low reverse stack. I installed alto heg frictions on all the clutches. My question is .065 too much clearance for the low reverse pack or will it be ok. Thanks for any help you can provide.

 

Rule of thumb is around .010 per friction. I would say it should be fine at those specs.

 

thanks brandon6.0, i'l go with that and get the case closed up, it will be spring before i am ready to install ,currently have a bto 2004r stage 2(for 12 years) and i am sure i will have some fitment issues on the a-body.thanks again.
