Someone told me once not toput a shift kit in a 700r4. Says that it can mess up the over drive. Is there any truth to this?

Thanks

Here is what happned to mine with a shift kit installed. Do yourself a favor save your self some money on the rebuild and just put a good ol 3 speed back in.

I ran mine for over 6 years including some rugged off roading and never had any problems. Maybe something was wrong with the kit. I do not know the type of kit that was installed, my friend that rebuilt the tranny installed it. I guess it is like any part you get some times you get a bad one.

I have never seen an automatic trans grenaded like that before! Definately a hard part failure or other cause. A properly installed shift kit, in an otherwise good transmission will help the trans. last longer.

I have a stage 1 shift kit and a corvette servo in my 700r4 and I am not having any troubles. I am running about 300 hp.
