Auto tranny hesitates on gear changes - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I noticed I think going from 2nd to 3rd at wot, the the tach stays at 6k longer than normal before it shifts. Or so it seems. Hopefully I'm not confusing 1st to second though.

I also notice that sometimes under normal driving the tach would start to slow down at 3k rpm unless you gave it a lil more gas, but soon as u let off and get back on it it slows down at 3k for a second, and starts climbing normal like.

What basically controls the shifting of the auto trans on 240s. I plan to get a flush even though I had new fluid put in like a year ago. However I think you can get a pressurized flush with a machine. If so I think I'm gonna get it done that way.

Other than that anything else like tps maybe or anything electronic?

Thanks for any help.
