When my car is cold the transmission seems to slip when going from a dead stop after about 2 minutes of driving it is fine and there are no problems. Any ideas what it could be i have not had a chance to check the fluid yet but it should be full I did a filter and fluid change about a year ago. It was rebuilt about 70,000 miles ago. It is a 700-R4

Check you TV cable first. I have the same issues. My tranny jerks when its cold, but i have no problems if i let the car warm up for 5 minutes before I go. Just a suggestion, would be a cheap easy fix.

Good luck and keep us posted bro.

This isn't going to sound right at all, but when cold sometimes this is normal. Not sure why, but when cold, some 700R4s will feel like they want to hold first gear longer, and may feel like they are slipping because it takes more to get them moving. Once they warm up a little, they are fine, and shift just fine. Now, pay close attention to this, and see if it is actually slipping, or just holding the gears longer. This will usually result in a harder upshift, because it is allowing more fluid pressure to build with the higher rpms. I'm not sure if it is due to sticking valves, or what, but I have seen some do this. I've seen others that won't. I've seen 4L60Es do this as well. Not sure why. Actually, watch a S10 with a 4.3L and 700R4 leave, and see if it doesn't sound a little odd when it is first leaving the line while cold. Just about every S10 with a 4.3L and a 700R4 does this, and so does the S10 Blazer with the 4L60E that I have. I spoke to a guy that has a 2000 S10 truck with the 4.3L and 4L60E, and he said that his does the same thing, and has done it since it rolled off of the dealer lot. So I'm not sure what to think of it. Anyway, try changing the fluid and filter and see if that helps. If not, then make sure it isn't slipping and it is just holding the gears a little longer until it warms up. If it is slipping, then you are seeing signs of other problems.

Its slipping not holding it basicly feels like i am moving fine then stops accelerating and goes again.

I also notice my steering wheel is hard to turn in the morning as well and it is fine on fluid but the temp is only 50 outside not that cold. If it was 30 or colder i could see this being a problem. But in the afternoon the steering is fine but the tranny still does its thing so i dont think it is tempature related.

When you pull the pan, inspect it carefully for anything odd that is in there. Also check the filter when you pull it off and see how it looks. Transmission flluid will thin out a little as heat is built up in the transmission and that will cause it to flow more easily, but transmission fluid isn't as suseptible to temperature as oil, and 50 degrees shouldn't be cold enough to do much to it.

Could be the TV Cable, I had the same problems with my 91. I had to let the car warm up a while if I wanted to shift properly.

My suggestion to you is if the car has high mileage I'd just change the cable, it wears over time and is a cheap easy fix that will help with yoru shifts.

I adjusted the TV cable when i did my oil change and also added a QT of tranny fluid and it seems fine now. Also the PS pump is fine when cold but the weather has been warmer.
