Going to have to make this quick as my body and bones are all the way into high range and over drive in the "we hurt" department.
Just finished executing a snatch and grab on the old TH350 that had been in my G-10 Van since the factory original blew its guts out at a service station that i used to use. Total puke all over the gas pump concrete pads. Needed a ro-ro to come and take it to a local T-mission shop. Johnny didn't even think rebuild, just yanked the corpse and stuffed in a replacement. Never was too sure if that second unit had been given a rebuild or if it was just a shelf critter with a check and go done to it.
Anyway, the old 350 came out without too much sturm und drang. Surprised me as I had thought it might fight back since this was a do it myself by myself operation. That was Part One for the day.
Part Two was to shift the old unit off the transmission jack and over to a flat dolly. Roll it out of the way and move the now empty jack up shop to the cherry picker, remove the 700R4 from the engine stand and deposit it on the jack. Then return the jack and load back under the van and attempt an install. Uh-UH. Come to find out that six layers of cribbing gives great me room but puts the jack out at the limit of its lift ability and beyond it unless a couple of sections of 2" x 10" got added to the tray to lift the transmission just that little bit more. Attempt numero two succeeded.
Which brings me to my question of the evening.
WHAT IS THE TORQUE VALUE OR SPEC IN FOOT/POUNDS FOR THE 700R4 CASE TO EN GINE BLOCK BOLTS AND ALSO FOR THE RING GEAR TO THE TORQUE CONVERTER???
Sorry about the caps; have been told that is supposedly yelling but it has been that kind of a long weekend. Absolutely NO help from the interwebs. The best I could discover was a guesstimate in the range of 35-45 for the case bolts and 35 -? for the converter bolts. As a total sidebar, when I went to remove those old converter bolts, I ended up having to remove the oil filter and use a 1/2 air impact gun; couldn't get enough room to apply sufficient leverage using hand tools and even my longest power bar, nothing happened. Air is wonderful, 6 point impact sockets that have been introduced to a lathe to shave them for better set down are even better. That tapered shoulder is nice but having full flats on the socket sittting against their counterparts on the bolt or nut is pure insurance.
So the 700R4 is currently solidly attached to the block using Grade Eight Capscrews fitted with flats and locks. The factory bolts were grade 5's with the "M" stamped in their heads. They were forty-one years old so about time to retire them methinks. The converter bolts are an ARP product and will get some locktite blue love before I set them into place and torque them.
Appreciate anyone on the board who has a proper and detailed reference text for factory torque values taking the time to post. As I noted above running a search engine for those values got me bupkus in useable replies but a lot of "expert" chest thumping instead. Had considered going to 50 for the case to block bolts given they are grade 8 and 3/8ths, plus going 40-45 on the converter bolts; with the locktite the 40 might be sufficient, but it is always nice to have a seasoned and learned opinion backed by a correct answer to work with.
Thanks in advance, Tylenol feels like it is starting to work so time for a major soak down and the rack.
