Hello... Couple questions for the transmission guru's around here. First off, My truck is a 2000 Ram CTD QuadCab Shortbed 3.55 gears all stock
61,000 miles. I plan on doing the 60k service which includes transmission fluid ,filter and adjust bands. The transmission seems fine...upshifts and downshifts great and no shudder or slippage. After talking to a couple shops ,seems like I have 2-3 alternatives to attack the transmission.1) Drop pan and change filter , reinstall and add fluid.Could also have shop lower valve body to get even more fluid out.
2) Leave pan installed and use a flush machine to circulate new +4 oil into the tranny.3)A local shop suggested using their flush machine to circulate,clean and refill using ATF+3 and a friction modifier (Lubeguard 63010) The shop owner has a Ram and said thats all he's ever done to his truck and its fine.He even went as far as to say Lubeguard gaurantees my transmission after the product is installed.
My choice so far is number 2....seems like using brand new oil throughout the tranny would be best,even though there is a downside of not changing the screen. My concern with this approach also is the flush machine connections at the cooler. Is there any chance of damage to connections or possibly loosening something that could cause engine coolant to contaminate transmission oil? Next question...do my bands need attention even if it seems to shift fine? Sorry for the long post and also,thanks in advance for taking time for me.
