TRNW-2: 700r4 aux v body --non aux v body

[preston farmer]

I have  a 87 truck with the date code on the side of the trans as 7,, meaning 87. The trans has a non aux v body on it with non aux pump. Someone built the trans 15 years ago.My understanding  was that all 87's had aux v body. Vehicle had been sitting for years,, don't know if trans didn't last long after being built. It has extremely hard rev engagement now with 75 psi pump pressure. Works good going fwd. Just wondering if the v body - case might be a problem and does anyone have pictures of any possible differences in the cases?
