1-2 Shift P1870

Postby DjPcEra [OP] » May 13th 2011, 1:29am

I'm going to drain the transmission fluid and change the filter hoping it solves my issue.

I will also add an additive.

Will keep posted with new updates.

:)

Edit : will I need some gasket sealer for this?

What transmission fluid should I use? Remember that I won't be flushing, don't know how, nor know if it would help.

It went in.... and still does the shift too slow..

I went to another transmission guy and he said there is a ball inside that gets stuck...

sometimes it won't get 1st and pass to 2nd shift... he said he would charge me 200$
