Transmission shifts hard until fluid is warm

Ask friends, relatives , co-workers which transmission shop they’ve used w/success. If you know some repair shop owners well, they can be a good source for this sort of info too. Usually there is one specific transmission shop in town that’s considered the best by those in the know. When I had my truck’s transmission rebuilt I asked a very good friend of mine who’s an auto repair mechanic who to use. The reply was immediate, no hemming and hawing. Next I made sure to tell the transmission shop owner that he (my mechanic friend) recommended me to their shop. Good results, perhaps slightly above the average shop price.

The KOM DA46 torque converter fits 1992-2006 Infinity I30 and Nissan Altima 2.4 L, not a Ford Aspire.

Dexron III/Dexron VI are the correct fluid.

Well thats good news. Where did you find that? Because…

click on the ‘Vehicle Fitment’ tab…“1994-1997 Ford Aspire”

I’m not even going to get into this again

Forgot to mention that the transmission guy broke the original torque converter when test driving the car or by doing a stall test. I didn’t fight with him about it because he had me convinced it was already destroyed and needed to be replaced

The torque converter should not fail during a road test or a stall test, if it does fail do you believe that it had a lot of life left in it?

He said he drove it pretty hard. If you read the thread it was only acting up due to the thermostat followed by the ECU, so driving it hard like that while it was acting up wasn’t the smartest thing. So yeah, it did have a lot of life left in it, just like the trans did even before the rebuild

A stall test is part of the standard diagnostic procedure, it is the technicians job to expose any weakness in the vehicle, not to baby the car and determine that it should be good for a little while longer.

A failing thermostat had nothing to do with the torque converter failure, the thermostat failure would only cause the computer not to engage lock-up, that would not cause torque converter failure.

BTW, I drive my car hard everyday, if there is a weak link I take care of it.

Alright man…

I said OR did a stall test. He definitetly drove it hard, really hard.

Him driving it hard the way it was acting did. Because when I got the car back after the rebuild, the problem was exactly as it was before he broke it. It would bang and jerk violently when letting off the gas at certain times. The check engine light didn’t come on until a week after I got the car back. I replaced the thermostat and the problem went right away
