It is the old style one with the round headlights though

The modulator is not to hard to replace. you will see a vacuum line runnin to it. sometimes when you put them in, the tranny doesn't shift right so you have to adjust them. their is a little allen head screw in where the vaccum line goes on. it's been a while but they are around 20 to 30 bucks

I have a 1987 G20 Van 305 automatic,turbo 400 tranny. I get going the tranny shifts fine til I hit 50mph then it starts to slip , I have done a filter and fluid change , had to replace the vacuum line...

It could be failing clutch packs or a failing torque converter. I had a TH350 that whined after upshifting to 3rd, then it quit. For me it was the torque converter. It took out the entire transmission, including the oil pump.

HOw do I find out how many vacume hoses are on an. Transmission for a 1997 ford contour and could a vacume leak be a problem for my transmission shifting hard ?

You have none and as for a vacuum leak no, Check engine light would pick up lean bank codes. aWhat you need to do is have the vehicle on a level ground engine warm vehicle in park check the transmission fluid,A low transmission fluid does and will cause a hard upshift as you have to raise the RPM. You should also change the transmission fluid with the filter. Also check the color of the transmission fluid it should be Red if its blackish it is burnt and the transmission service will not help you.

Modulator possibly went bad

use a Mityvac or any type of vaccum pump vaccum tester tool (avail at ay parts store) and hook it to the vacuum nipple of the vacuum modulator on the side of the trans, pump the tool to see if modualtor holds vacuum, if it doesn't it is defective.

Vacuum line on top of my 4l60

some trannys have a hard line that comes out on top of trans. all your old 350's and 400 turbos had them, thats just a breather tube for trans., it don't hook to anything. just a breather. i believe thats what your talking about.

Transmission shifts extremely hard.I had trans rebuilt, still

The Buick (GM) Corp, has offically released this as an on-going problem with this style of tranny, but will not issue a recall. Basically, it can only be fixed by replacing the pressure valve within the tranny. This is a costly fix (400 to 650, depending on the shop). The pressure valve (over time) wears a groove between the valve cylinder wall and piston (of valve) which allows tranny fluid to bypass thru the line, thus causing the hard shifting, mostly when the tranny is hot and the fluid is thin. Trust me when I say, no other fix will work, such as changing tranny fluid, flush and fill, or any additives such as Seafoam or other tranny slip or fix additives. Bite the bullet and find a tranny shop which will give you a LIFE TIME warranty, mostly, in case they install yet another defective valve.
