Re: transmission
Long hours suck, I know how it feels. I put in a few long weeks to catch up for the Christmas season so I could take Monday off. Hope your days get better.
When I rebuild a 700R4/4L60E I use what's called a "Z-pack" option in my rebuild kit. The factory 3rd gear pack has 7 clutch discs (I think), and the Z kit allows for 9 or 10 to give it better holding/shifting and less chance of burning up under a load. 3rd gear pack is the weak link. If there's too much gap between the clutch plates, it will cause the engine to rev up between 2/3 shifts. Shimming the gap between the backing plate and the retaining ring is very important.
If the 3rd gear accumulator has a weak spring in it, it too could cause a funny shift. I do a lot of performance work on trucks and Camaros, when I build up a 700R4, I usually make metal spacers for the 2nd and 3rd gear accumulators. It stiffens up the shifts w/o having to buy an expensive shift kit. There's a lot more tricks I've learned over the years and I could post a lengthy reply, but I won't.
Have the guy pull the pan and check the 3rd accumulator spring. If you can flex it w/your bare hands, I'd say it's too weak. If he rebuilds them on a regular basis and has a box of spare parts, find a stiffer spring or stack a bunch of big washers in it's place.
I have repaird several broken pipe flanges, seems to only happen on the right side. I have a pipe machine, so I can make a new flange and weld it to the old pipe w/o any hassle.
There's never an easy fix w/tranny probs. and it's never fun to fix a problem twice. I hope the tranny doesn't have to come back out.
Post back on what happens.
