Sure it's a 350? 82 was the first year for the 700. If a 350 the wires are for convertor lockup.

Re: 69 chevy trans swap ?
Could be a turbo 350c which has a lockup converter. Don't know much about them, so I'm no help there.

Re: 69 chevy trans swap ?
nope its not a 700 at all what you got is what they call a th350 c its basically a 350 turbo with a lockup converter 81 was the last year for the regular th350 my 85 silverado had this transmission, you can upgrade it and it will work however nothing th350 wise will work for it in the line of rebuild kits or shift kits you would be smart to use the lockup convertor and wire the lockup switch b&m offers a kit for this or i'm sure you could do it yourself still a decent transmission but i'd rather have the old th350 hope that helps you

Re: 69 chevy trans swap ?
ok i agree the trans has the lockup converter now but any suggestions why it takes off in drive instead of 1st unless you manually downshift it?

Re: 69 chevy trans swap ?
well maybe the vacuum modulator??? i doubt it would have anything to do with the detent cable and i assume it coming out of a van it wouldn't have a manual valve body so i'd check the line to the vaccum modulator and look for a leak maybe might even change modulator, i don't think having the lockup unhooked will have any affect on the shifting no reason to

Re: 69 chevy trans swap ?
I'm not convinced that you have a th350c as you might have a 700r4 or a 2004r. 82 was the first year for the 700r4. The easiest way to tell is to look at the bottom of the transmission pan and match it to one of these on this website.

Re: 69 chevy trans swap ?
yeah but i would assume that the van he got it from only had the 1 2 D selector on the column instead of one that said 1 2 3 OD, another way is that he is driving it and the R4 has a different tailshaft length and i'd assume he would have had to modify a driveshaft to ran the R4 and not the th350c as its the same length

Re: 69 chevy trans swap ?
Actually a TH 350C would be longer than a correct TH350 from on of our trucks. All of ours have short shafts, and after the mid 70's (maybe even 73) they were all long shafts, so some shaft mods are still needed.
