99 sedan ,120,000 miles with automatic tranny. slips,surges trying to shift from 2nd to 3rd occasionally. not always.

Check the transmission fluid with the engine idling in neutral. If the level is good, and the fluid appears fairly clean, then you probably need to visit a repair shop. A low fluid level can cause shifting problems.

I'd do a Seafoam flush and filter myself first. Cheap/can't hurt anything..might work

xt I'd have it checked out WITHOUT taking it apart.

If that doesn't work I'd get a used trans from the bone and put that in.

high mileage flush = bad news in some cars. i also own a 1998 chevy lumina. most all the members over on the lumina forum agreed it,s certain death to the tranny to first time flush with high mileage. i think they said anything over 60,000 . anyone try to add about 1/2 of pint of seafoam(no flush) and have good results ?

I agree..NOT some..MOST!/pretty much all transmissions..and have posted/written extensively about it.Here.

Uh..yours is a 99 Escort with 120,000 on it. THIS transmission in GOOD shape is worth about $200 used.AND YOURS is slipping..yours is worth?? Core. you are worried about damaging it???

Seafoam trans. flush is VERY! aggressive. Iirc they reccommend you leave it in for about 5 miles then flush it.

My neighbour is a distributor I get it CHEAP..haha.

Like he said to me..and I agreed. "Yours is cooked. What harm NOW can Seafoam do"?.

Ah..If I hadn't used it..and posted about.. using it on a trans(Escort) that had severe problems(slipping/seizing up)..and was toast.. with about 250.000 on it..AND having had it work successfuly for another 100,000 (still worked fine when boned) do you think I would have reccommended it again??
