I have a 1999 OBS Suburban and it's going in tomorrow! Anything to look out for? Anyone have tips on the easiest way to do this? Any help/info/insight is appreciated

 

A transmission jack makes it way easier. Other than that its pretty much straight forward

 

Do you have to disconnect the cooler lines or the 4L60's wiring harness?

 

Yessir

 

you pretty much have to drop the whole tranny to drop in the converter.

 

Pretty much?

 

well truck is back home now but there's a MASSIVE problem. The stall works great, flashes right up to 25~2700 just like Chris said it would and pulls hard, but when the truck goes to do a WOT shift, it bounces the rev limiter once or twice going 1-2 and just revs for like 3-5 seconds going 2-3. I would say the transmission is doneskies, but it was shifting crisp and strong when I dropped the truck off. Only things I had done were the stall, Vette Servo from Circle D and I told my trans guy to put a set of stock servo springs in instead of the springs that my Transgo HD-2 shift kit came with and told me to install. I'm hoping that the issue can be traced back to the springs, so I'm going to put them back in today. I'm really disappointed/ concerned about this problem and any insight into the issue would be greatly appreciated.

 

yea thats not good... pretty much means its slipping..... get another out of a junk yard... or do an 80e swap with that big tank of yours... what motor is in the truck???

 

Did you get a re-tune for the converter????

 

What he said^ did you have it tuned...
