i was a quart low on fluid so i thought i would dump a quart of trickshift in thier (non -synthetic) in their. now it seems its harder to make it downshift when i need it too. and my first/second shift doesnt seem as hard either. would this additive cause that?

 

i've always use trick shift in my trans with no problems but I used the full synthetic I hear the other trick shift is no good

 

I thought??? the old stuff was very similar to type f atf (old ford stuff)

 

it was the son synthetic crap i put in it.

i read the back carefully and it says it is compatable with all crap. and at the bottom it did say it meets or exceeds type F standards as well though :\ so i dunno. my tranny prolly gonna blow up.

 

if its the old stuff look at the bottle it says not for use in ODtransmissions.so if you have a 700r4 that could be the problem

 

it didnt mention anything like that.

 

good, sounds like you have the better stuff

 

Trick Shift is basically rebottled Type F tranny fluid. It has more friction modifiers in it because the older Ford trannies (71-80 ??) have smaller clutches requiring more friction modifier to engage them.

 

you killed my transmission

 

trans fluid is not the culprit.
