[RESOLVED] 420a tranny fluid

[Shameless]

I've read posts about turbo models and what tranny fluid to use but little to no posts about for a 420a. I've been told Redline MTL or MT-90 is the best stuff and I've also heard BG Syncroshift II Full Synthetic is the best. I truly am inexperienced with choices of gear oil, this is my first dsm, switching over from a truck so if anyone could help. It would be nice to know, I'm in the middle of dropping a new engine in and the last few details I'm trying to figure out.

Call your local dealership and ask; I believe questions are for free.

The NV-T350 transaxle has paper backed synchro's for gears 3, 4 and 5, and requires the use of Mopar NV-T350 fluid (dealer part #04874465) or ATF+4.

Use ONLY these fluids in your 420a's manual transmission.

^+1 This is the reason Jiffy Lube (or similar clone franchise) will get very confused and hesitant when you ask for any type of tranny fluid replacment. Most have conflicting information as to which type of fluid to use.

well when I went to one of the better auto supply store yesterday, the person to call was at lunch. The supply store is the only reliable store as far as parts or assistance goes. Asking the dealership gets me no where, thats why I ask you guys because I've always got an answer to my problems.

Stay with Post #3. Don't try any voodoo magic on it.
