You guys are great! I appreciate the advice.

I'm still concerned about using the 722.4. I've read that the 722.4 was only used in the 190's and my friend says that this one did come from a 89 190 with a 2.5 turbo. The same motor that's in my 93 300d 2.5turbo. Does anyone know if it's true the 300d 2.5's only came with the 722.3. and if so, do you think the 722.4 would hold up over time in it's place. We don't know how many miles were on the 89 190, only that it was shifting fine with no apparent leaks. I figure the cost for purchase and swapping out the two at app. $600 compared to a rebuilt of my 722.3 at a cost of $1200 to $1500 by a local shop with a great rep. The car has 125k on it and I plan to keep it, but like everyone else don't to spend money I don't need to.

I've considered rebuilding the 722.3 myself with the help of a another good friend who has built a number of gm automatic trannys. I'm sure there are significant differences, but do you think the ATSG manual would be enough to get us through this. I've priced the kits from $250 to $500.

Sorry for all the rambling, just trying to get my head around all the issues.

thanks
