Any Tips for Imporvement on a 4R70W?
 

I have a 4R70W in my Mark VIII and I'd like to improve its perfromance, but it slips in 1st and 2nd when cold and just womdering should i worry about this?

I was think about installing a Shift kit to help improve perfromance and is there any thing elese that i should look at, and I doing it on a College Student's budget.
By the Way, My Mark VIII is stock.

P.S. I know my sig say otherwise.

you should worry or at least be aware of any slipping. I would not do any kind of shift kit, etc. when there's a slipping issue.

The trans is worn and needs to be repaired unfortunately, and adding any valve body mods will likely make it die sooner.

Thanks for the tips, do you know other comapny that sell or rebuilds 4R70W besides TCI, Art Carr or Hughes that is pro-touring-ish not street/strip or should i tried to have a local transmission shop rebuild it?

Dylan try these guys - http://www.bc-automotive.com/index.html

I have the valve body and converter from them for a 4r70w. Good quality and service.
