To start off, my 95 mustang GT has suffered a few injuries. The loss of my 4th gear being one, so I bought a transmission locally! Supposedly it has 55,000 original miles on it, and it looks pretty clean, but all I need it to do is run. The pathetic part is, this happened while spinning at 5300 rpms on a barely year old rebuild (just barely out of warranty as well). A friend of mine was passing me on an open highway (spare me your morals) in a volvo s90 I believe, so I gun it, considering her car it was suppose to be an easy pass up followed by a casual ride home. Then, *boom* slipping. I slide it back into netural, and back into drive, it kicks to third, all good, kicks to fourth, and gone, it spins freely as the rpms climb.. But anyways, my real question is, should this be a swap I should be doing by myself, or should I have a shop do it? I feel like it wouldn't be impossible to raise the car high enough and wheel in the new transmission and torque converter. However, I've been wrong before. Also, how much would you estimate a shop cost for something like this? (pulling the old, putting in the new) for a transmission shop I'd imagine 3-5 hours of work. An additional question I had, while the old transmission is out, if I was planning on 4.10s or 4.56s gears later on, should I change the speedo gear now?
