Mitsubishi Diamante TCU  



 Repair & Return Service $250. including return shipping 
We usually only keep it one or two business days, depending on time of arrival and the amount of time and attention any particular TCU requires. The damage on these can vary quite a bit, so it's all about what we have to work with when we open it up. 

To purchase a remanufactured Diamante TCU from our inventory, call us with the part number you need.

Attn: '92 owners:
Before sending in a '91-'92 MD740087, MD739228, MD751888, MD758085, or MD758086
for rebuild and return service,
please check the main processing chips on the circuit board for signs of the examples below.
If you have either of these on your TCM, it will not be repairable.
There is one large chip and two smaller ones on these.

 
This is the classic bubbled chip,
it is possible to replace the chip, but it is not available for replacement


This is a sneaky one, the brown center burnt chip,
this is easy to miss, sometimes it is very faint, not as obvious as this one,
but it is still a board killer.


We charge $35. for inspection plus return shipping cost
(but only if there is no sale or repair,)
