You do need to remove the old crossmember if it does not line up, but first see how much clearance you do need and if there is any way to use the existing crossmember because of where it bolts up to the frame. Maybe just cutting off the orignal trans mount from the crossmember and remounting it may give you the clearance or even turning it around to see if can be used. That way you are not spending any extra money that you don't need to. You last option is to cut crossmember and design what you need as a crossmember that works.
I hope that me input helps you.

I have a 2001 HONDA CIVIC LX 1.7 5 SPEED I use as a oval race car ok what would be making it go in limp mode

I see this a lot on cars that folks use for "non transportation" uses(racing) , I assume that u left the diag port in wire harness (hope so cus now you need it ) plug a code reader in port and look for major faults , could be as simple as a part u took off to gain some Hp (catalytic convertor) or clearances for speed equipment (turbo) and the stock brain box didn't like it being taken away !!
code reader are so cheap nodays every one should have one , ive even got one now that wirelessly connects my smart phone to car to ck all that ales it while u drive wow !! and it wasn't expensive

Removal of 1990 gmc serra 4x4 transmission

with the assumption its an automatic the following applies(if a manual youll need to remove the slave cylinder from the transmission, its located above the starter) 1.Disconnect the battery and place truck on jackstands if needed for clearance and remove the starter 2. Remove front and rear drivelines as well as speedo sender and and shift linkage (remove shift lever if manual and transfer case shift linkage if not push button, you should be able to just seperate the linkage from the ****** and transfer case and leave the linkage dangling) and any other electrical connections to ****** and transfer case (such as push button transfer case, and electronic automatic trannies) make sure to scribe a line or mark the drivelines in relationship to the yokes so they get installed in the same position for balance 3. Remove transfer case, this will take some of the weight off and make moving the ****** around much easier on you 4. Beggining with the top bellhousing bolt remove all but the bottom two bellhousing bolts (save those for later, one on each side) 5. youre going to need a helper for the next part unless you have a transmission cradle for your floor jack support the transmission with a floor jack remove the crossmember bolts from the frame or completely remove the crossmember from the equation,, either way works 6. remove the two bottom bellhousing bolts from earlier, the transmission is now free, you will have to wiggle it around some and **** it as sometimes the splines on the torque converter bind up, sometimes in low clearance applications you need to support the motor with hoist, remove the motor mounts and drop the motor slightly to get a better angle. sometimes the ****** will pop right off and sometimes you have to fight it a bit but thats the way it goes, just remember the ****** is heavy so be carefull if not useing a ****** cradle! hope this helps out, good luck. also i recomend buy a chilton service manual for any do it yourselfers, its only about 15 bucks and covers alot of stuff, such as removing the ******.

How to put new oil pump in 4.6 thunderbird

You will need a service manual (Chilton's Haynes) for all of the correct torque specs and the correct disassembly/assembly sequences. That being said, the oil pump is a big job to change. You will need to disconnect the motor mounts and transmission mounts and raise the engine up so that the oil pan will clear the crossmember. If you can't get clearance doing that, the engine will need to come out. I would check the oil pressure with a mechanical guage to ensure that it indeed as low as it appears to be before beginning the endeavor.

Can I replace my 700r4 in my 1992 GMC Sierra with 350 turbo tranny out a 1985 GMC Sierra?

I did, but I had to exchange the drive shaft b/c the length was wrong. the R4 has OD, and the 350 does not, making the 350 shorter. It's no a great idea. I was unhappy with the 3 speed 350 because of very poor gas mileage, so I went back to the r4. I had a bit of an issue with the speedo cable and the tranny crossmember mount too. It's not really worth it, but yes, you can do it, but it's going to take fab work, and after my own ordeal, I'd not really suggest it. I was just trying to save a few bucks, and got myself into a world of hurt. lol you live , you learn. Unfortunately Fixya did not exist back then.

On a '96 Jeep Cherokee 4.0L 4X4, do you have to remove the exhaust or crossmember to remove the transmission pan and does the dipstick tube seperate from the pan?

You shouldn't have to, but check for clearance before you start. The height between the bottom of the pan and the cross member should be more than the height of the pan itself.You may be able to gain an 1 or so, but using a jack or the front of the transmission bell housing and on the output shaft. DO NOT try to support the weight of the vehicle, just try to gain a little clearance if needed.

How to remove a transmission?

Hope this is not your first, if it is you picked a tough one to learn on. Here goes:1 disconnect negative battery cable 2 Raise and support the car, a lift is the best tool for the job here, but you can do this on jackstands, they just need to be tall ones at least 2 feet of clearance under the car. 3 Install engine holding fixture, this supports the back of the engine when you remove the crossmember and trans.4 remove left front wheel, seperate ball joint remove drive axle retaining nut then remove drive axle from transaxle by prying at joint closest to transaxle. Do not pull on the outer joint or you will pull the inner joint apart. 5 place transmission jack under transaxle pan. 6 remove bolts from crossmember then remove the crossmember 7 remove inspection cover then remove three torque converter bolts 8 remove transmission cooling lines from fittings on transmission 9 remove shift cable 10 unplug 4 wire plug from front side of transmission 11 remove 6 bolts from bell housing 12 remove speedometer cable 13 remove three bolts from around right hand drive axle, then pry axle loose from transmission. You do not need to remove axle from car, just let it hang.14 pull transmission away from engine far enough to disengage the alignment dowels and finish pulling right hand drive axle from transmission housing then lower the transmission to the floor 15 pull transmission from under vehicle.

How do you change the transmission fluid in a 2004 GMC Yukon Denali?

At the bottom of your transmission there is a large square/rectangular pan (depends which trans you have). Have a large drain pan to catch 5 to 9 liters/quarts of transmission fluid. Undo all of the retainer bolts and carefully lower the pan (this can get messy for the unexperienced) .
In some cases the rear transmission mount may need to be undone and the rear of the trans lifted to allow clearance for the pan to be slid past the crossmember.
Replace the trans filter too!
