#37 of 78 Transmission problems?? by 91buick Apr 03, 2007 (10:16 am)
I have a 91 buick regal with the 3800 v6, lately when i start slowing down to stop at a stop sign the transmission acts like it has shifted into neutral cuz once i try to get going it will just rev up then it will shudder and go into gear and go normally, the motor doesn't stop running anyttime during this. Lately it has been taking more to get it going again, sometimes i have to shift into neutral then back to drive to get it to go when trying to leave a stop sign, the tranny fluid is up to the full mark and everything else seems alright, do i have a tranny issue or brake issue or possible injectors???? anything would be appreciated!

Replying to: exo425 (Feb 21, 2006 11:45 am) I read with interest your transmission studdering problem. I have the same problem with a 91 Regal, 265,000 kilometers. The transmission guy tells me its the overdrive lockup and the tune up guy tells me it's an ignition problem. How did you make out changing the coil packs?

#39 of 78 4T60-E Vacuum Modulator Location by spangler May 16, 2007 (8:43 pm)
I have a 97 Regal GS with a factory rebuilt 4T60-E & I can't find the vacuum modulator. I saw on previous posts that one person said it was on the front right side (driver side) of the transmission when facing the car. Well, I can't find it or a vacuum line.   Maybe the rebuilt 4T60-E don't have a vacuum modulator?   I went to Mitchell's & the exploded view didn't even show the vacuum modulator, but did mention part 47 which was not on the view.   HELP, transmission shifting hard and not shifting right.

Replying to: bsheppard (Apr 21, 2007 11:32 am) after changing the 3 ignition coils, spark plugs and wires, the car has been running great ever since. The problem was that only one of the coils was burned out so the car essentially was running only under 4 cylinders at a load. the car would studder because it wasnt balanced. I am happy with the way the car was running but i must add that the total bill for the repair came out to about $600. Replies to this message: bsheppard (Jun 06, 2007 1:20 pm)

Replying to: exo425 (May 28, 2007 5:40 pm) replaced two coils on my 91 Regal and the car is working fine, thanks to this forum. Many were convinced it was the transmission lock-out, even the local transmission specialist. Thanks again
#43 of 78 99' GS hard shift by roysanders Jun 29, 2007 (7:33 pm)
Recently my 99 GS has intermittant hard shift problems( up or down). Once every 3 or 4 days. Usually after shutting off and restart seems to shift just fine. Is this a Speed Sensor Problem or something a lot worse? Replies to this message: foreigncarguy (Aug 16, 2007 6:45 am) foreigncarguy (Aug 16, 2007 7:07 am)
#44 of 78 New Radiator HATE THE TRANSMISSION LINE by erwisneski Jul 18, 2007 (6:10 pm)
Okay I replaced my radiator this weekend. 135k on the od was about time. Replaced it with a 1 1/4 in radiator. Radiator works great. Lower transmission line... Not so good. It leaks. I checked the threading on both and they both looked PERFECT. No angle threaded happened. Anyway it is leaking through the hole in the middle of the nut. I put in a temp fix and but teflon tape on the white junk. Works great for now until the heat destroy's it. I looked at the flare and it looks good had a friend also look at it and he saw no problems. I assume he knows he restore Falcon's . Should I purchase a new Tranny line. The upper seemed to mate good. Let me know appriciate the help as always.
#45 of 78 about transmission of my car. by vcmaster Jul 22, 2007 (6:45 pm)
I bought a 2000 BUICK Regal LS on July 9th. The mileage is 86000. The price of BUICK is 3600$. My car runs smoothly. Last Friday, the battery of my car is used up, and I found that the stop light is always on. I drove my car to Firestone. The technician did an inspection of stoplight switch, and told me that the stoplight switch is worn out. Because they did not have a stoplight switch, they unfixed the stoplight. On Saturday, I found that transmission of my car has some problems. When my car is run at a low speed, and then speed up, these will an instantaneous tremble. Does the stoplight switch inspection cause this problem? I do not know how to deal with this. Would you please give me some advices? If the mechanical inspection is needed, would you please recommend a store for me? Thanks.
#46 of 78 Big problems with 95' Regal by amerigo Jul 23, 2007 (10:34 am)
I have a used 95' Regal that was running just fine until recently. I got an oil change a few weeks ago and had my transmission fluid topped off. I suspected that was related, but now am unsure.   Over the last couple of weeks the 95' Regal has starting jumping as it switches gears, more and more violently. As I was taking it to get looked at, it went out of gear completely into neutral while I was driving and I had to stop and start the car again to get it back into drive. When I got to the mechanic, they checked the fluid level and everything was full and fine as far as that was concerned - they recommended a transmission specialist.   Has anyone else had these problems? Any suggestions?
