WILL A 1998 4L60E FIT MY 2001 SILVERADO?

I had a similar problem with my 1997 XK8. Apparently the transmission will not last much more than 100,000 miles. You need to replace the clutch in the transmission - cost between $2,500 and $4,000.

No they will not interchange. The input shaft pump and converter are different. Internal parts will interchange. You will need 96-early 99 model That is old body style.

Yes, but the steps involved in switching the 4wd output shaft, over to the 2wd output shaft are very involved. Thats assuming that the bellhousings are identical. (detachable bellhousing) That you do not need a 30 spline input shaft for your torque converter (96+ blazer input shaft splines are all 28 splines, however you may need a 30 spline in order for the correct torque converter to fit your 2wd vehicle.) You will need to know what 2wd output shaft you need, there are quite a few variations. Then you would need to take the pan off, pull the shift soleniod blocking access to the lockup soleniod, remove the lockup soleniod, remove the pump bolts, pull the pump, unhook the 2nd/4th, band remove the reverse drum - 3/4 drum (by pulling the input shaft twards you) then remove the yellow snap ring holding the output shaft in place. Now the output shaft is able to be removed and switched. Re instalation of the drums/pump is tricky as well, as all the clutches need lined back up to slide back onto there corasponding splines. Long story short, it would be alot more trouble than its worth. : )

SOURCE: what model 4L60E tranny's can I put in my 1998

the way i figured which 4l60e works with my truck was to get the service number off of the ecm. Then I took that ecm service number and searched for it on ebay. People selling that same ecm will usually list what other vehicles that ecm works on. Then I went to the u-pull&pay and got a tranny out of one of those vehicles. I do know that after 95 there is an extra pin in the main wiring harness that goes to the PWM. My 94 tranny didn't have that pin. Also try pulling the main wiring harness out of your tranny and with a mirror look down into the tranny and get the pin configuration. Make sure the one you get also has that same pin layout.
