Transmission Replacement - DIY or Shop?

[john330]

anyone know how high the car has to be for the transmission to clear?

My jack stands can reach around 17 inches. is that high enough or do I need new jack stands?

I'm looking at doing a tranny and/or gear box rebuild, and would happily offer free assistance to one of you guys in So Cal who may be thinking along the same lines.

Team,

I have a 2004 Boxster and am in process of removing the 5spd TX. Have removed everything as per the articles and am using the compressor (120 psi) and airtool but none of the bolts are budging. Is it normal, are they supposed to be that tight? Have applied PB Blaster over the late few days but to no avail. If I can't have B budging, I am wondering how I am going to remove D with the added loss of the socket extension?

Is it always that one has to use a long length ratchet or something and undo the bolts? The torque spec is not that high.

Any suggestion, comments will be helpful and appreciated.

I just swapped out my transmission over the holidays and found that the trans bolts were pretty tight. I used a 1/2" socket set and an 18" breaker bar to get them loose. Of course, its hard to say how tight is "tight" and how hard to push is "too hard".

To get to the upper bolts, I used every possible combination of u-joint + short or long socket + extension(s) to find the right setup that made getting each bolt out easier. You'll find that there is room to get to each bolt, you just have to find that good location and then match up the right combination of tools to reach.

My experience is about the same as "Thstone" My advice is use as few linked socket extensions as possible. Each joint reduces the impact and torque by 10-15%. Use the socket and one extension were possible with your impact tool. Best advice is purchase a IMPACT extension set with at least 4 sizes to fit your most common applications (Money well spent). The shanks are stiffer and flex less and the squares are less likely to deform. Common chrome extensions that come with your standard sockets flex too much for a 1/2" high torque impact.

+1 on an 18 inch breaker bar.

With the snorkel removed you can reach all the top bolts very easily from above.

I found many bolts that my air wrench would not turn until i had at least cracked them with the breaker bar
