Ok, Got an '02 GC Larado 4x4 stock 4.0 with no mods, that i'm aware of.
When the engine is cold right when the engine fires there is a obnoxious clunk or bang. It's not as noticeable when the engine is at operating temps, but still there, but only at startup.
Now the basic Q's
I'm not sure of the transmission ID as it's dark right now, I suppose I could wait till morning to go look but...
I want to service the trasmsmission (since I have no idea when or if it was ever done) When it's cold it doesn't shit very well, rpms gotta be around 1700 -2000 depending on what mood she's in. What are the owner/operator/performance guy recommendations on fluid type, filter(s) etc. - Including the front and rear transfer cases - in the reasonable price range please?
Also -( geese this guys got a lotta newbe Q's) What are the thoughts on these performance "chips" for engine and transmission?
As always, thank you in advance! (Whatever happened to Please and thank you anyhow?)
