Early shift

[Qxx4]

Hi again guys so i encounter another problem the other day the car was at the mechanic because oil seal between the engine and transmission was bad and he changed the trasmission fluid with ac delco type three fluid and now when i floor it from zero it shifts not at 6000rpm but at 5600 so i mean its shifting earlier than usual could this be because of the ac delco fluid?

I doubt it's from the fluid. Those transmissions should be fine with using regular dextron III. Perhaps the fresh fluid is actually making it shift how it was intended rather than how it did prior to the work.

Don't know about the fluid difference -- I always use the Nissan D-matic. But .. I do know you are doing your transmission no favors by flooring it and having it shift at those RPMs .. just don't.

You will be buying a new one shortly if you continue.

Srry for being late but this problem usually happens only when it shifts from first to second but all the others shift normal and It dosent shift hard or anything could this be an ecu problem ?
