OK, been awhile but I still have the old girl since day 1 and I hope to keep her for awhile yet. 196 000 Km's on her now. I'm an Amsoil fan and pretty much have it everywhere in her (that sounds funny)
Background: I switched over to Amsoil ATF 20,000 Km's ago and would like to just drain/fill the auto transmission once a year, basically cleaning 40% of the fluid, rather than taking it to the dealership.
1. Following the shop manual I took the level while the vehicle was idling and warm, looked good, in the 'hot' zone of dipstick.
2. Drained the ATF, got just over 4 US quarts out? Here's the thing, the manual says it should only be 2.5 US Quarts for the A43D, 1.7 US Quarts for the A340RE, or 2.1 US Q for the A340F?
3. I measure out how much came out 4.1 US Quarts, I put back in 4.1 US Quarts go for a drive, heat things up, and take the level while it's idling, looks to be on the edge of the hot knotch, pretty good.
Comment: I could of sworn I saw a post from someone who seemed to know what they were doing and said he drains 4 US Quarts from his auto trans on the gen 1, can't find that post now.
She's running fine, went to Montana this weekend, seems to be running smooth.
Question: Should I drain it and put 2 US Quarts in and go from there, or am I fine?
Driving me a little crazy.
Thanks in advance for any help.
Kind of a mechanical hack, just get by doing the easy stuff like fluids, grease and plugs.
