700 R4


When I shift into reverse, especially when I first start the car for the day it takes a few seconds to get in gear. normally about 4 seconds. On the first ride of the day its take up to about 20 seconds to get in gear. Tranny level is full of fluid. I do park on about an 8 degree hill. If anyone knows how to fix or what is causing this issue I'm all ears.

 

Not that it matters much, but can you clarify, is the "first time of the day" lag time 4 seconds or 20 seconds? Since you mention your "first ride" as well as reversing, does that mean it's also slipping in the forward gears?
There are only a few things that come to mind that it could cause slipping.
1) Low fluid level, which you say it's fine.
2) The pump (under the front cover of the trans) could be going bad, or
3) The clutch pack inside the trans is worn out.
If the trans has a bunch of miles, I'm going with the clutches as being your problem. They eventually wear down just like a standard cluch does. As the trans and fluid warms up, it gives the clutches just enough friction to grab. But, it's going to get progressively worse until it just won't move any more.
You can put in a trans additive (friction inhibitor) that's made to treat a slipping transmission. In my experiences, I'd say that chances are pretty good that it will help. If the additive does make a difference, then you'll know the clutches are the culprit. Be prepared though, because the additive is only a bandaid that will only buy you a little time, and then a new trans or rebuild will be in your future.

Its about 20 seconds lag for the first ride of the day and about 4 every other ride. And it does do it in drive as well, but it only takes about 3 seconds max to get in gear. I do have a 350 turbo tranny with a new torque converter I can put in. I dont know if it will bolt right up to the 305 and I dont have the money to put it in and no resources to do it myself. Thats why it has not been done yet.
