My ford aerostar van transmission is not catching ?

Question

my friend was over here and he said it was probably a transmission sensor but i dont know about cars it revs up to like 5000 rpms then catches help tahnks

Answer 1

Check the vacuum line going to the modulator valve on the transmission. If it is disconnected you will have late upshifts.

This particular transmission model (A4LD) does use a modulator up until about '95 when it was changed to electronic controls.

Answer 2

not much info but mite be low on fluid or the band and or clutches are bad. could just be a plugged filter.

Answer 3

its a ford and most of them dont have modulators thats on gm trannies and since its a ford the most likely cause is the bands and clucthes are goin out but try a filter change it may help  

Answer 4

not enough info to answer., what things have checked?
