need to replace or rebuild my 5r55w... what to do?

[PUR PONY]

Im in the middle of replacing timing chains on my 06 4.0 and while the transmission is out i need to do something with it. The servo case bores are worn. I currently have 40+K miles on AJ1E OD servos with the o-rings and so far so good... but i know the min i put this truck all back together the o-rings will fail (thats my luck)! So since the transmission and t-case are out, what should i do? Have a local place ream and sleeve the bores and do a rebuild or should i just buy a rebuild / re-manufactured transmission for it? Ive read remanufacture is better then a simple rebuild. Are there any reputable places online to order a 5r55w from? just looking for some input. thanks

How many miles does the transmission have (the total amount)? WWW.Transtar1.Com has remanufactured transmissions. You could get a quote from a rebuilder that's listed on WWW.ATRA.Com.

You might want to rebuild it while it's out of the vehicle.
