Auto transmission hesitation

[Hyper_Mike]

Hey guys,

So this started happening yesterday. Going from stopped and then accelerating (even slowly) just before it changes from first into second gear it seems to hesitate for a second and revs without seeming to put and power to the wheels. Then it changes into second and all of the other gears perfectly. Down shifting is also perfect. Fluid was changed about a month ago and has been working fine.

Any ideas?

Cheers, Mike

Did you replace the filter at the same time?

What fluid was used? And was it a case of dumping the sump contents then refilling?

+1 As Tim asked. It seams to be lacking line pressure. Bleeding for too long.
Add a 700ml bottle of Lucas transmission fix. Very thick stuff.
Cheers

Yep filter and gasket were replaced at the same time

Also, it only seems to do it once the car is warm, for the first 5 or so mins its fine and working well, then after is seems to start doing it.
I ended up using the Penrite Fully Synthetic ATF. I will try the Lucas transmission fix Aldo

Hey Aldo,

Should i just add it to the existing ATF? or drain and put new stuff in with the lucas?

Just add it.

clogged injectors needing ultrasonic clean?
