Hello all,
Have some tranny questions. I have an '06 LBZ. Noticed my tranny cooler lines leaking so Im gonna chage them..While Im at it im goona change my tranny fluid.. 1st how many quarts does it take? I read in the maunal 25? Does anybody know the model of tranny that come in the GM (automatic)? I know Allision suggests a certain type of synthetic oil but from what I could tell it would be about $600 bucks for 25 quarts..Is that right? Oh ya my truck has 30k miles.. Thanks!

Welcome to the forum! :drink

Im honestly not 100% sure how mutch fluid it holds. That sounds like a awful lot. IIRC that might be the total amount of fluid. You wont get all the out of the trans with the torque converter and trans cooler using fluid.

But. my truck had the cooler lines go with 25k. Is your truck still under the 3 year warranty? While your changing the fluid remember to replace the internal filter and might want to put a transgojr shift kit in if you have any modifications. Im doing that to my truck soon and puting in stock fluid :cool:
