problem with power after fixed tranny?
ok, I just got my car back from a local tranny place and now I got a question for you guys. They said it was a "sprage" that they fixed and I just picked it up and it seems like it doesnt pull as hard as it did, my boost gauge used to max at 10psi all day, now the most it will hit is 8-9. It is definetly noticeable. So my question is, is there anything they could of done that would cause loss of power when they were fixing my tranny? I checked the vac lines and they seem fine. I am so pissed I spent $1200 on the tranny and expected my car to run as it did, should I call them back or do you guys have any ideas what might be causing this, from a dig it just doesnt seem like it used too.Please help!! Thanks guys

Re: problem with power after fixed tranny?
We would just be speculating and too hard to tell. However, it is quite obvious if they replaced a sprag gear then the tranny was pulled. But that shouldn't affect the engine and why you have a perceived loss of power. Did they do any other work to the tranny?
Just to be sure run an engine vacuum test and see if vacuum is in spec. 15-22 in-hg.
