hi,
ive tried searching and come up with nothing. i was just wondering if the 700r4s had any diffrences throughout the years, i know there were slight improvements, but what does that include, valve body, etc. mainly what i was really wondering was are there diffrences in the gear ratios at all.
thanks
Joe

 

ok, sorry about the inconvinience, i just found the list of ratios on the tech pages.

sorry again for the unnesessary post

The ratios never changed. 82-83 and some 84 units had the smaller input shaft, some 87 and all 88+ units have the auxiliary valve body with the extra accumulators. There were additional minor changes every year it seems.

 

82-84 have the 27 spline input shaft and the 84-93 have the 30 spline input shaft. 93+ 4L60 and 4L60E's have 30 spline as well.

 

the 84-97 had 27 splines if it was a v-6.

 

Yes, but nobody cares about V6's.

 

lol...i gotta agree with that one

 

the new models (seems to be more like 86-1/2)are 30 spline input, have more forward clutch packs, better input sprag and better planetaries. Plus the previous models would burn up very quickly if the converter didn't lock-up, and don't usually have the "auxilary valvebody

 

The spline count changed long before the auxiliary valvebody was added.

If you're looking for a core though, definitely look for an 87+ model.
