700R4 transmission 2nd gear slip

[plutopjf]

I had a 700R4 built a could of years ago and may hav 8K miles on it. I had it built to handle up to 500HP. I had a Corvette servo installed for first gear.

Here is the problem:

As I start off in first gear at a slow speed it would hold first gear for a while and have a crisp shift to second. Now I notice it just slides into second and second gear doesn't seem to have as much pulling power. It is like second gear is slipping. It shifts good into third gear and pulls hard.

I changed the filter and fluid. The fluid looked good and red like it should. I don't know what to think.



Any ideas?



Thank you,

Paul
