99 SSEi #1 (my first SSEi)
Orig trans lasted 136k miles
Rebuild again at 142k miles
Been going good ever since and last I heard had 180k+ over a year ago.
98 SSE (My 3rd SSE)
Bad solenoid, but didn't repair/replace solenoid. Still going strong and I see the car on the road every day -no doubt it has over 210k miles now.
99 SSEi #2 (2nd and current SSEi)
Original trans bad at 119k -snapped input shaft)
current trans is from a 00 GTP and has 43k miles and is doing well with a Transgo Shift kit.
02 Park Avenue Ultra (Moms)
95k miles and still going strong
04 Park Avenue Ultra (Dads)
91k miles and still going strong
97 SSEi (brothers)
230k miles and has a bad 4th gear, doesn't want to go into gear until car is warmed up.
97 GTP (cousins)
265k miles and is missing 2nd gear, otherwise is doing well.
99 SSEi (sisters)
105K and it has a bad solenoid -clunks on take-offs every so-often.
98 LSS (Brothers old one)
206k miles on original trans and it shifted/operated like you'd expect a new one to.
1997 Park Avenue (was mine, then Dad'*, now Uncles)
Bought with a bad transmission at 130k'ish miles IIRC.
Replacement trans had 70k supposedly and has close to 150k now and as far as I know it hasn't given any problems since installation.
