I just changed my tranny fluid from Redline to Amsoil ATF. First I noticed a big difference in smoother shifting. But I also noticed that the low end trq is not there. Michael Wan will hopefully chime in on this one. So smoother shifts Bad low end trq Before when I would tap the pedal from a stop it would put me back in the seat. Now when I do it, its just too smooth. No trq.

 

Man, I dont know bout the "No torque"....... I want some low end torque

Please uppdate us if it the car react differently after a few miles.... Thanks

 

Did you just do one drain/fill with Amsoil?

The main question here is whether the transmission behavior you're currently experiencing was also experienced with Honda Z1. In other words, when your first bought the car, did the transmission function this way?

You can try resetting the TCM by disconnecting the battery cables, and having it relearn your shifts.

 

Must of been the computer, car is back to normal, with smooth shifts. Got a little scared at first, but torque is back.

 

Yep, that's sometimes normal. The computer takes time to "adjust" to the new fluid. If you reset the TCM, that speeds up the process.

 

I did a semi flush. I drained and filled 3 quarts. Drove around for 10min, and drained and filled once more. I am resetting the transmission control unit now.

 

Ok, I spoked to my mechanic about the lose of torque and he couldn't believe the loss torque... Too bad i ordered the redline from comptech earlier.. wish i can cancel it...

 

Does this Amzoil ATF meet the Honda spec for ATF? I wasn't aware of any synthetic ATF available that met the Honda spec? Please double check. Thanks.

 

No low end TQ? If its slipping you will loose power. This is why you don't mess with the Honda ATF. I sell Amsoil as a dealer, but will not mess with the tranny on this car.

 

The torque is not gone anymore. The computer just relearned my shifts. Everything is good now. I like it.
Meets honda Z1 specs.

Correct it does meet Z1 spec.

 

I've been running this fluid for 22,000 miles and no problems.

 

How many quarts does the TL require?

 

If you read the Amsoil ATF specs, it meets and exceeds all the requirements of a Honda ATF Z1 specs. However, if you compare the charts and the numbers between Redline ATF vs Amsoil ATF. Redline products EXCEEDS Amsoil....... but then again... those are just numbers. Personal experience counts and seems like eric has been running his car in Amsoil ATF for 22k and no problems. Paul recently shifted to Amsoil and seem to have better shifting. Meanwhile I have Redline and had hard shift before, but since lubeguard, it's been fine.

I will change to Amsoil upon my next tranny fluid change.

Thanks for the heads up Paul
