I have this same problem, try this...start the car, and shift from Park to Reverse wait a second, and then to drive, in my car when I do this it doesnt jerk. I just replaced my transmission...thinking this would fix it and it didnt. I dont have a good answer, just wanted to know if it is the same problem. Mark P.S. It could be your motor mounts, or trans mount, I replaced mine but it didnt fix the problem. Try the shifting thing I mentioned up top, if yours still jerks when you go from P to R to D, then it is probably a bad mount. Mark

Wow, very nice. Thank you. I actually did the swap today, I am almost done, just need to torque the exaust, top off fluid, and install the front splash pan. I did start the car and run it through the gears, but I think the fluid is still to low, because it would'nt go into any gear, or I messed up the torque converter. It's been a long day...8 hours with my hands above my head. Again, THANK YOU. Mark

Thank you all very much, I have looked at the rear main seal replacement, and I have a good idea. I didnt know about alldatadiy.com, I will look at that. I appreciate all your help, have a great day and I will let you know how it went in 8-9 hours. Mark

Lets start out by saying I am new to the site, this has probably already been posted, but I could not find it so please forgive me if this is a repeat question. As the Topic Title says, I am looking for (as close to step by step) removal and installation proceedures for a 1994 LS 400 transmission. I plan on doing this tomarrow. My LS 400 has 251,500 miles, and for about a year the transmission has been going into gear hard...I start it and move the shifter from Park to Drive and it grabs very hard and shakes the car (all mount have been replaced), the strange thing is that if I shift from Park to Reverse, it is very smooth, and then from Reverse to Drive it is smooth, to make a long story short it has been in and out of the dealer, and they have no idea, I have been thinking about just replaceing the whole transmission but I am a single income Navy guy with three teenage boys, so money is always tight, last week the transmission started making a buzzing noise, so back to the dealer, they said the front pump is going out. I found a transmission from a friend of a friend, so I trust it is good, I have access to a auto hobby shop here on base, I am a good mechanic, I would just like a little help, so I don't end up breaking something. Thank you in advance for any info you could supply. Mark
