How does it shift when just cruising around.About quarter throttle and under 3500rpms..Adam

when im real gentle it shifts fine, like starting from a stop light... when im crusing it will kind of hesitate... hard to explain. its acts like it wants to shift... and will after a few seconds unless i let off the gas and then it will shift. if  i mat it it will just climb and not shift until i let up... all the way then it still takes a few secs.

should the tv cable be real snugg/ stiff cause it was super loose. i could pull the the end of it prob 1/4 or 1/8 of an inch (something like that... felt like alot of play on something like that) before it felt like tension.

It should be tight- if it is loose, the cable will do nothing.

The detent cable is used for downshifting and upshifting in low vacuum situations like three qurater to wide open throttle.On the front of the transmission under the turbo is a modulator valve.That controls upshifts and downshifts by vacuum and it can be adjusted.I would check the metal line that comes from the plenum and follow it to the valve.Make sure it has not been chafing on anything and developed a leak.Also check the rubber lines and make sure they are not split or cracked.Most likely the modulator valve will not need to be adjusted but I've seen it a few times.Hope this helps  :icon_biggrin:  Adam

I tell you what: mine was doing the same crap until I did two things: Tightened the TV cable and changed my Coils. Trust me, they are spendy, but they are needed and worth it. This is exactly what mine was doing, along with a bunch of other crap. BTW I solved my tranny problem: The aftermarket tranny cooler line slipped off and spewed fluid everywhere...again. lol. it was just the other line this time...Put some Wynn's tranny solution in and after a while it sounded great again.

Oh yah! :icon_cool: It was a pain to figure out where it was leaking from...cuz we had two tranny lines going from the trans to the radiator, and then two additional lines going from there to the little cooler. After washing away all the fluid and water and snow and all, we found it. Replaced the tranny lines and put new couplings on, and new clamps. Some tranny fluid and some Wynn's and she ran great again!

Awesome- what's wynn's?  Never heard of it.   If it is a tranny additive like Lucas, I suggest you get it outta there ASAP- drain the tranny fluid out, replace filter and put new fluid in, NO additives- additives kill trannies.

Yes it's an additive, however it's not your normal additive. I can't remember exactly how it works, all I know is my dad's Jeep had a tranny tht was acting up bad a few years back...after adding this it hasn't reoccured once.

Dusting off this old topic. I just found out one of my coolant lines either to or from the turbo is leaking, and probably leaking as the fitting on the turbo. It's the line closest to the engine, or, when looking at the engine from head on, it's the left line. Not sure if it's the return or feed line, but it's wet, and leaking...so...What stops this? LOL.

O rings? There were none with the turbo, and none removed from the turbo. I used plumbers tape on the fittings when I screwed them into the new turbo this spring. They didn't start leaking until a month or so ago, and we just today figured out that it was a little farther up the line than where we thought it was. Any suggestions?

Oh no!  The thread returns! :laugh: jk
I know I said this before, but I'll put it in writing.  When I removed my turbo last winter, both my coolant lines leaked, as well as my oil return spigot.  I took and cleaned up the surfaces where the lines mount to the brass spigots and where the spigots screw into the turbo.  I poly taped where the spigots screw into the turbo, then took o-rings and placed them where the coolant lines screw into the brass spigots, finally I poly taped the coolant lines themselves, and tightened them all together.  You may want to tighten them more later, as the orings will settle a tiny bit and may leak.. that is how I got my coolant and oil lines leak free.
Hope this helps!

Well, not to worry lol. Turns out that the fitting somehow came loose on the turbo. They're going to tighten her back up and check the fluids, then it's good to go!

Alright, so I fixed a few more problems, and I figured that this thread CANNOT die!

The hard shifting/bucking problems were due to a bad transmission vaccum modulator valve and a lower transmission mount having gone out. Both fixed and the car shifts great!

I also replaced the alternator and it fixed my flickering/dimming lights problem.
