Dear Cadillac Enthusiasts,

I have a 1998 Seville STS with around 82K miles. My mechanic found the transmission in need of service...fluid change, filters, etc. Although the transmission life indicator continually reads 100%, I'm fine with the service because I purchased the car used and don't know whenthe trannywas last serviced. Nevertheless, my mechanic quoted me around $250.00 for the service which surprised me, and I placed a delay on the work. I called a transmission shop which offers the service for $40.00. What a huge disparity...any thoughts? I'm going to go with the transmission shop, unless y'all think there is something I'm missing.

Many Thanks,
alan

If you don't know how old fluid at 82 k its most likely worth changing, however 250.00 is a little much. Northstar transmission or 4T80e has cleanable screens and re-usable gasket.So only parts required should be fluid if gasket is ok.There is a filter within side cover of transmission which only be replaced during major repair or overhaul. I would expect something in the 100.00 to change it add 50-75.00 for gasket if needed. Trans shop sounds too cheap like they maybe setting you up for a repair maybe not,but I would check their rep. first.Hope it helps

i just had my sts...'99 done it was $80.00 or so..... thats a pretty normal cost for that, i think slowroll will agree.......any case, get it done for sure......
