Quick question DRDD, ...no codes yet...but why change the tranny oil/filter, maybe waste my time and $$ if no reverse is in it for sure that a rebuilded tranny is needed????

Fluid and filter is probably a waste.
No reverse + No 2nd + No 4th = Reaction Shell = Rebuild or replace

i'd like your opinion ...you've answered my post before regarding a tranny problem ( ses lite, no reverse, 2nd ou 4th gears) I got the code, only 1 code showed up : P0753 ' shift selenoid A electrical'. I went to see a couple of tranny '' experts'' both say that I need a new tranny: the reverse shell probably stripped, sent metal shavings to the selenoid bay, with made it code and loose 2nd and 4 th...But I know I lost 2nd and 4 th BEFORE I lost the reverse. Should I have the selenoid, oil & filter changed, approx 200$ or I'm wasting money. The ''experts'' tell me i wasting good after bad and should a rebuilded intalled. All I want is to be able to sell the jimmy...
