have patience... sort out the problems using stock parts before jumping into the torch route. if the tranny is acting up start with a fluid and filter change... sometimes this will cure problems if they arent too advanced. a sorted benz is worth a lot more on resale than a modified one especially with a chevy tranny.

buy a good repair manual and work through problems one at a time and try to avoid throwing money at it.

good luck.
