What else is wrong just changed tranny fluid filter and gasket now tranny slipping never slipped before?

Answer 1

depending on how old the trans is, and how many times the fluid has been changed, you could have a real problem, over time, with a transmission, actual particles of the transmission tiny bits of metal, have become loose, and float around in the fluid, actually making the fluid thick and dense, now this particle packed fluid, if left alone, will continue to allow the trans to operate properly and maybe reduce, daily problems, but its only a matter of time, before this dirty fluid, causes transmission failure, This happened to me, with a Ford Windstar Van, auto trans, van had ninety thousand plus miles, totally unaware if fluid had ever been changed, so i changed it, completely, and put all new fluid, new filter, and the next day trans started to slip, then worse the next day, and so on and so on, It was explained to me, that if you have your trans checked by a pro, and he says its okay for you to change the fluid, then you must change the fluid, on time, everytime like clockwork, if he says dont change the fluid then you dont change it, just add fluid when you need it, removing all the fluid basically removes the broken bits of gears and parts, and when new fluid is put in, the gears that once operated correctly, dont because, the clean fluid, doesnt protect the teeth, and now the gears slip, Dont quote me on this next statement, but my R&R guy said if your trans is old, dont change anything, just add fluid , if its new, then follow your owners manual, recommended maintenance schedule I hope this helped you, In conclusion, I highly recommend a trip to AAMCO or Mr. Transmission, and have it checked right away, new trannys, installed, cost 2200.00 with no warranty,
