lol it wasn't pretty iselhondas, neither was what i ended up having to do! i ended up bolting a chain to the 3 points it bolts to the flywheel, using boards to make a little platform and force it with a bottle jack till it popped off! the bushing inside the torque converter was shot, and the seal was destroyed. The input shaft looked a little scuffed too. So after some deliberation, and chatting with the owner, we decided it'd be best to go with another trans. (we also discovered some metal shavings in the pan, so yeah) I did ask around imidazol97, and a few people told me i shouldn't have much trouble getting it off unless something was damaged keeping it there. Thanx everybody! ^_^ -Aaron- |

Last week we saw a stain/spot right under the transmission near the left tire. Drove the car on ramps and checked for leaks and found nothing. No leaks over next 4-5 days and 150 miles. Tomorrow when returned home there is even bigger spot on the driveway at the same location but again nothing dripping. However, when it leaked, it must have been coming down relatively fast because the stain shows that fluid ran few inches down the driveway. Do we have a transmission leak (car has 31K miles, transmission fluid was changed last year around 26K)? Do 4T40-E or similar GM tannys behave like described? By the way no change in coolant, brake fluid levels, no gasoline odor and no motor oil. The stain/spot looks somewhat greasy but completely dried off in 3-4 days after the first incident without leaving any permanent visible stain. TIA

Replying to: kiawah (Oct 02, 2007 8:46 am) I am planning to take a closer look at those transmission to radiator lines and find out if they are leaking or not. |

When Im driving off for 10min, the OD Off light starts to flicker on my automatic transmission and my gears seems be shifting to lower gear or dont accelerate even if you yank the gas there it seems that the transmission is locked to second gear or lower, it tried to on and off the OD button or shifting still have the same problem, sometimes this happens sometimes not but mostly it happens. What seems to be problem? 1) Is it the Computer box for the transmission considering this is 1995 model? 2) Do you think the sensor on shifting the gears have some problem? 3) According to my friend their might be clog on the filter for the transmission fluid which sends out a wrong reading to the computer thereby shifting it to lower gear mode? Can you please help me out on this problem. |

Hey everybody, Some of you may remember me asking about problems with a 95 monte carlo.(3.4L) (my first question was about the torque convertor being stuck) I'm back to ask another question. I swapped out the 4T60-E trans for another 4T60-E Off a 98 Buick LeSabre First off, the Monte Carlo trans was running fine, but was dumping trans fluid from the input shaft. The Driver apparently ran it hard even after it lost the fluid from there and destroyed the bushing in the torque converter (causing the torque convertor to become stuck to the input shaft, and extremely hard to remove!) There was also the tell-tale blackish crap in the trans fluid, so even though the trans seemed 2 run ok still, owner decided it was time to 2 get another trans. The LeSabre trans was very clean (the car was running great, and was involved in a front end wreck (did not damage anything more than cosmetic), so was parked and used for parts. Everything is identical with the exeption to the side pan, which is used as a mounting point on the monte's pan (i used the monte's) and the shafts (also used the monte's) ok, so the details. The side pan also had another difference. The LeSabre's had i believe 6 bolts on the pan around where the cv-shaft goes in. in order to use that pan, i also had to swap the shift solenoids and pump (all integrated) The monte's uses a o ring, no bolts around the cv-shaft area. So here's where it gets funny. I got everything bolted up and ready, filled the trans, check everything again. Start it up, runs fine. Goes into gear fine, shifts fine when driven, at first at least. Then driving down my little street, it'll drop into 2nd or 3rd, and refuse to shift out of it. I can put it in neutral, park, reverse, back into D or OD, and still goes to 2nd or 3rd (not sure which, but it's really weak) and won't get out. If i turn the car off, start it and put it into D or OD again, It'll start in first, and drive normally. But shortly after, again drop into a higher gear and refuse to shift. Any ideas? Did i forget something? One other thing i forgot to mention, I thought maybe The shift box that sits on the shifter (on the trans) might have something to do with it, but tried both the original, and the the LeSabre one (which is identical, with the exeption of the wire that carries power to the starter) and with a little creativity, i connected it, but it did the same thing. Also as a side note (i don't know if this has anything to do with) The owner apparantly made a "cool air intake" with the tubing you can buy at autozone, and there's a black vacuum tube that is connected to the side of the intake tube, and runs accross the intake (under the black plastic over the injectors) to the center left of the engine. It also runs around the driver side of the engine, around the egr electrical stuff, between the intake manifold and firewall, where it appears to go nowhere! O.o i taped that sucker up, cuz it was just open! The owner actually mentioned the car didn't want to start right away usually. I didn't start nor drive the car b4 i worked on it, but it starts right up for me, so i suspect he was running that open as it plugs into the intake tube, on the engine side of the Mass Airflow Sensor. Which makes me wonder if there's possible damage if he was running it lean this whole time... but does anybody know where that vacuum goes? like i say it's sorta just hangin there... Lengthy, but i tried to include everything i've done, i know, and etc info. I appreciate any knowledge, info, advice! Thanx  -Aaron-
