i sold my 87 300sdl to my friend, the trans had been acting up but the kickdown switch had a bunch of junk clogged up in it and i thought that was the issue after doing a lot of searches and reading

the trans will be perfect for while and then wont shift, runs up to 4000rpms, etc

i had it at the indie shop for 8 days and they could never get it to mess up at all
, then i cleaned the swicth area, etc hoping that was it

anyone have a good recommendation for a shop in tucson or phoenix that has a lot of experience with 300sdls, the vaccum stuff, etc

this indie shop i was using is pricey and since it never acted up they did not even test anything
i think they tend to focus on newer cars etc also

at this point i would like someone else to look at it
