need advice

[idaho270]

I have a 67 f100 with 352 engine. Seems like the past few weeks of being relatively cold outside, i have a little slip going into reverse and drive. Not quite sure what typr of tranny i have but suspect it is a c6?? I will sit and warm it up for about five minutes and she seems to slip out of gear like she is still in neutral. once i get on the road about a couple miles it seems to work itself out. checked tranny level and all seems okay.
could this be just a matter of warming up??
thanks

There is a problem developing, let's figure it out...First, we need to be sure what trans you have.
Then let's clarify if you have a DELAY, as in not applying .....engine can rev up & you feel no movement of the truck, OR
You put in gear and try to accelerate & the truck is moving but you feel that it is SLIPPING or not moving as you would expect it to. ?
You say that you can let it warm up for 5 min & all is OK , or it still has a problem ? Not clear on this???
I am not quite sure where you are, post back with answers & be specific, there are a LOT of "if's" in the answer to your problem.
need more info & I or someone will try to help you.........Donnie

are you checking the fluid level cold or after its run up for a bit,cuz if the fluids cold the dipstick will tell you its all good whenit really isn't (i.e. you're running pretty low)

Another very important thing is to look at the directions on your transmission dipstick. Your truck must be warmed up and still running when you check the level. I made that mistake before and thought I had plenty of fluid, only to find out later that it didn't even register on the dipstick when the truck was running.
