Question about 1988 Ford F 150

Open Question

My transmission slips into neutral when I slow down and or come to a stop. I won't do it when under power. Is there an adjustment that needs to be made?

This is a transmission that I replaced myself several years ago and ran fine for a year or two. It was a rebuilt tranny from Checker Auto (at the time)

SOURCE: Trans clunking when slowing down

Sounds like youi may have a few serious problems going on to have that kind of back lash occuring at higher speeds. I have experiance with low spped clunks on Bronkos and your type of vech being a car dealer. One you might try for low speed clunk on take off and braking at stop likts just completeing a stop? Pull the drive shaft and lubricate the splin - two check your leaf springs for weakness and wore bushings - take a look at your shocks - three u bolts holding springs to rear axle housing may be letting the axle housing actually dip or tweak or all those thing in combination - now you may have some serious slop in the pig - transfer case may be causing that clunk - as far as high spped clunk and activity you have a serous problem and you just might drop the transferr case have an accident fliping over..............Mike South Bend Indiana don't just keep driving and making problem worst...........

it depends on the trans but ford had alot of problems with though years with the overdrive shift kit it is a band in the trans and it pop out and break you need to take to local trans shop and let them look at it and tell them the problem and they will take the trans out and crack it up and replace the part that need to be replace before you have to replace the whole trans the ford dealerships dont have the best trans people hate to say that but it true take to someone who specialize in trans only

SOURCE: auto tranny wont shift out of first gear

Sounds like the modulator or a vacuum line..
The modulator tells the trani when to shift and is controled by vacuum presure..
Check for damaged or disconnected vacuum lines stemming from the trani..
Or maybe the modulator linkage is stuck..
Changing the fluid is a good idea too..

Transmission is not shifting in 1 or 2nd only. park is good, reverse good, neutral good, motor is not hot, fluid smell and looks good


when your fluid starts to turn dark and you'll smell the fluid,you will know if it's burnt,this happens when the bands gets loose and out of adjustment,as your coming to a stop with your foot off the accelerator pedal and the vehicle starts to slow down the band will help the transmission to slow as well as the vehicle,but if the bands are loose and not tight enough,your clutch's will try to slow the vehicle,when this happens the clutch's will not hold and start to slip,and this will burn the clutch's as well as the fluid,after this keeps happening the clutch's will start to slip when you start to take off from a stop,and will burn the clutch's even more,now your in need of a transmission rebuilt,so when you notice the fluid starting to smell and turn from red to dark red or black,the best thing to do is take it to a transmission shop and have the fluid and filter replaced,and have them adjust the bands,if you try this at home the fluid change should not be a problem but the band adjustment is a different story,if you don't follow step by step and tighten the band's too tight you can break the band's and that will make a for sure thing that you will need a rebuild,so just because the fluid gets burnt doesn't mean you need a rebuild unless you have driven it to long.

My 84 Bronco seems to go into neutral when I slow down or come to a stop.


Hi there,

This is a classic condition of a 'slipping' transmission.

The problem could be anything from bad fluid, poor fluid pressure, faulty pressure valves, faulty solenoids, loose bands or even internal mechanical failure.

First step would be to flush your transmission and refill with new fluid and replace the transmission's internal oil filter.

If problem persists, then a transmission overhaul or 2nd hand replacement could be in order.

Truck lost power and when you try to pass a car it slows down and chuggs


Stop trying to do what you are doing!!! Sounds like the transmission is slipping when attempting to downshift, and engine is over-revving!! Check the transmission fluid level and correct if needed. If fluid level is correct and fluid smells burned, suspect transmission has internal problem.

Put a new engine in a 1998 isuzu rodeo now it won't start. I thought it was the neutral safety switch because the R was on the dash and it was in park


This could be the problem. If your dash indicator is showing reverse but the transmission is in park it could be the safety switch. I'm not talking about the safety switch in the transmission though. In automatics they put a second switch to kill the starter from engaging. You need to adjust the linkage. If your shifter isn't actually on the column but the indicators are there is a cable that attaches the floor shift to the column and that is adjustable. Put the Floor shifter in Park and turn the column section nearest the dash by hand until you find park. Then adjust the cable length as needed. If all you have is the column shift it is still a cable adjustment. Set the emergency brake, drop the shifter to low 1 and adjust the cable linkage by loosening it on the transmission and manually move it all the way to low 1 then tighten it down then move the shifter to park and repeat teh adjustment process to verify that it is properly aligned. Lock the linkage back down and see if the vehicle will start, if it doesn't move the shifter to neutral and try to start the vehicle if the vehicle starts then check the column shift safety switch at the park position to make sure it is still in place and working. Typically, if the vehicle won't start in Park or Neutral it is more likely to be the Transmission neutral safety switch.

Mazda starter switch in park Car starts in neutral, but won't turn the starter in park. Battery is fine, its a1999 6cyl with automatic. Intermitent problem


You need to replace and adjust your transmission range sensor switch. (also known as neutral safety switch) It is located under the air cleaner ducting on the top of the transmission under the lever where the shifter cable attaches.
