Default 95 SLE Transaxle installation

The "new" trans is in and so far, seems to be working swell. I wanted to post some pix and let you all know how I got this done. (This may not be the best way, but it worked for me!)

Thanks to Jr's3800 and mkaake for helping solve some problems along the way.

Jack and blocks

and finally, some notes:

Engine hangers can be purchased for about $200. Some places rent them (but not in my town) or you can build one. Plans with drawings are here: http://www.bonnevilleclub.com/forum/...=306016#306016

I used an engine hoist to lift the trans with a chain installed using bolts tightened near the balance point. It may be OK to just roll the trans on its side to change the filter and clean the pan. (?)

I had to be pretty aggressive with the old pump seal to get it out. It was necessary to distort and destroy the old seal to remove it. I used a heavy screwdriver with a pretty sharp tip - kept the angle of the screwdriver low to the face of the seal so as not to hit any of the shafts or the case. There is about a half-inch of space behind the seal. Got the new seal started and used the PVC pipe to drive it in. Kept the pipe in contact with the full face of the seal and struck the other end of the pipe where the seal was out the most - had to hit it pretty hard to get it to seat.

My replacement trans had a longer shift lever than the original (column shift, maybe?). Held the lever with a big Crescent wrench when doing and undoing the nut. I changed the lever for the old one and also used the old neutral switch because the wiring looked better. I positioned the old switch on the new trans using the marks on the switch from the mounting nuts as a guide.

The fitting on the end of the vinyl hose on the aerosol can of cooler flush was way too small for the trans cooling line. I cut off the fitting. The i.d. of the vinyl hose was about 1/4" and the o.d. of the flared end of the steel cooling line was about 1/2" By heating the end of the vinyl hose with a heat gun and spreading it over the cone shaped nozzle on my engine cleaner wand, I was able to get it big enough to start and stretch over the bigger diameter flare on the cooling line to make a good seal.

I tilted and blocked the trans under the car until I could get a little scissors jack and board underneath it. The jack was from an old Mustang - it is only about 4" high when all the way down. I used this jacking and blocking method because I was unable to lift the trans onto the floor jack and plywood board when it was under the car.

When lifting the transaxle, I used a board on top of the jack to distribute the weight so I didn't dent the pan. I kept the jack under the trans until all the mounts were in place and could safely hold the weight of the trans without distorting or stressing the trans case. I spun the jack as needed to get better access as I worked, but didnít release it until all the mounts were tight.

With the torque converter in place, the balance point end to end is at the face where the bell housing attaches to the engine, the balance point front to back is best judged by looking at the trans from the driverí* side.

I should have installed the front mount on the front crossmember BEFORE I installed the cradle half. Would have saved me a half-hour taking it back down to do it.

Tightened the vehicle speed sensor and dipstick tube holddown bolts from the top of the engine by lying on the engine.

When filling the transaxle, I put about two gallons in, then started the car, then added a pint at a time, checking the level frequently until the level was correct. It took a little more than 2-1/2 gallons to fill.

Thanks. Yeah, I'm not real bright, but I can still learn. When I called this junkyard, I asked them to read me the ID tag (didn't give my numbers) before I agreed to purchase. When I heard 5BXW, I figured we were good to go.

Thanks again, mkaake, for your help.
