I've had my car back for about a week now and I would definitely like to recommend Accurate Transmission in Aurora for anyone needing some transmission work. They treated me very well and were very willing to do what I wanted at each step of the process. They also were very up-front and honest with everything and did not try to sell me anything I didn't really need.
I ended up just having them pull the transmission for me and do the rebuild since I ran out of time to pull it myself. They were fine with me just bringing them the trans too if I had gone that route. Cost for them to pull the trans, tear it down, replace the bad parts, replace the clutch and flywheel and put everything back together was right at $1200 for labor. The parts were additional on top of that and would obviously vary depending on what needed done. They used OEM parts in the trans and I provided them with a CM FX300 and SMFW. Had I decided to do the OEM clutch, they were fine doing either the DWFW or converting it to the SMFW/WRX clutch and would have covered either under their warranty.
All of their work is covered by a 12 month/12,000 mile warranty except for when parts are provided by the customer (my trans is covered but the clutch is not).
In addition to transmissions, they are an (almost) full-service repair and service center and will do anything from oil changes to full overhauls (except brakes). My mother has used them for all of her automotive needs for nearly 15 years and now that I have experience with them as well, I can certainly see why.
The manager, Chad, is who I would suggest asking for if you are calling to inquire about anything. He is very knowledgeable and friendly. The owner, Bob, is also good to work with but he is semi-retired and not around much.
They are located at: 1040 S Joliet St, Aurora, CO 80012 (about 1/2mile east of Havana and Mississippi on the north side of Mississippi behind the Firestone shop)
